Investigating the Relationship Between the Lengths, Perimeter and Area of a Right Angle Triangle Coursework Aim To investigate the relationships between the lengths, perimeter and area of a right angle triangle. Pythagoras Theorem is a² + b² = c². 'a' being the shortest side, 'b' being the middle side and 'c' being the longest side of a right angled triangle. So the (smallest number)² + (middle number)² = (largest number)² The number 3, 4 and 5 satisfy this condition 3²
Description of the Performer The push up is a skill that has been used in many fitness tests that are used in many educational settings. In these tests the skill is allows the same technique. The performer will do one push up without any corrects or demonstration prior to performance. The performer is capable of doing a traditional push up. The performer is 21 years of age. The performer would be listed as physical fit in many of the fitness test. The learner is a high stage of development due to
should be in the standing position. 2. The subject’s head should be in the midposition (facing straight ahead). 3. The grip size should be adjusted so that the middle finger’s midportion is approximatrely at a right angle. 4. The subject’s forearm may be placed at any angle between 90 degrees and 180 degrees of the upper arm; the upper arm is in a vertical position. 5. The subject’s wrist and forearm should be at the midprone position.
The results were quite accurate, but could be more accurate by doing an average of more than five different sets of results. This could also be a fairer test by making sure the string the pendulum is attached to is exactly 90° (right-angle) from the clamp stand. Doing background research into the pendulum I found that Galileo was the first to properly experiment on this work. He discovered that a pendulum with a length of string four feet long would have a period
1-1 Vertical Angles Theorem Vertical angles are congruent. Theorem 1-2 Congruent Supplements Theorem If two angles are supplements of congruent angles (or of the same angle), then the two angles are congruent. Theorem 1-3 Congruent Complements Theorem If two angles are complements of congruent angles (or of the same angle), then the two angles are congruent. Theorem 2-1 Triangle Angle-Sum Theorem The sum of the measures of the angles of a triangle is 180. Theorem 2-2 Exterior Angle Theorem The
When researching the math behind sports, I found that there are a multitude of formulas that go behind the simple actions in sports such as basketball and baseball. Basketball is a game played between two teams of five players in which goals are scored by throwing a ball through a netted hoop fixed above each end of the court. Baseball is a ball game played between two teams of nine on a field with a diamond-shaped circuit of four bases. To be successful in these sports, one must make their baskets
and Rotation * Angles Once I had my ideas, I asked the teachers in the department what they would prefer the resource to be. Most thought that reflection and rotation was easier to teach than the others, and that more resources were available to them for that area of mathematics. The general consensus was that either of the other three was fine. So I have chosen to base my resource on angles with some properties of quadrilateral and triangles as supplement to the angles work. A factor
laws of physics, such as the law of gravitation. Sometimes, we might wonder how kinetics might apply in the Pokémon world: Team Rocket is sent blasting off again! They are struck by Pikachu's lightning bolt and are initially thrown at a 60 degree angle with an unknown speed. We do however know that they “land” in a body of water 114.5 meters away (assumed to be leveled) 6.363 seconds later. What is the speed that Team Rocket are thrown and what was their maximum height? Assume no air resistance or
well as figure out the best angle to send the ball where it needs to be. Throwing a deep ball is all about using the right angle with the right amount of force. I want to find out at which angle is the best to throw the ball the farthest. The angles I will test will be a low angle at 15˚, a medium angle at 45˚, and a high angle at 75˚. The force throwing the ball will be the same and the tight spiral will be assumed constant, so the only factor changing will be the angle at which the ball is being
apparent positions of objects produced by a shift in the position of the observer” (Columbia Electronic Encyclopedia 1). Parallax is commonly used to measure distances between celestial bodies, such as planets and stars. Parallax is measured using angles that are much smaller than a degree. Arcminutes are one sixtieth of a degree and arcseconds are one sixtieth of an arminute. One example of the infinitesimal size of an arcsecond could be the width of a dime from a point of view two kilometers away
the prism will not be refracted since the angle of refraction = sin-1(sin(0)/n) = 0, or reflected, so the images will be exactly the same. More generally, if the rays enter and leave a prism at right angles (Assuming the rays only travels through one medium while passing through the prism), the only effect on the image will be the reflection of the rays off of its surfaces. Since the law of reflection I= -I’ (Angle of incidence equals the negative of the angle of reflection) is not effected by the medium
parts of the world to see places most people will not, or perhaps some places that most people do not even know exist. I am going to make an attempt to do some extreme activities in an attempt to experience life from another angle. Again, an angle most people just do not see, an angle hopefully a little too far off a tangent the average person. To experience life and take advantage of it, one needs to make promises to oneself. A person may wonder, “How am I supposed to do this? How can I possibly accomplish
an image, and asked them to rotate it mentally by a certain angle, and then match the rotated image with one of several choices. Their prediction was that the greater the angle of rotation, the longer the task would take. This was because it would take longer to physically rotate a figure more degrees than fewer degrees. The evidence supported this hypothesis: The closer the angle is to 180 degrees, the longer the reaction time. Angles greater than 180 degrees do not take longer because the subject
There are multiple methods that can be used to find the sides and angles of a triangle, such as Special Right Triangles (30, 60, 90 and 45, 45, 90), SOHCAHTOA, and the Law of Sines and Cosines. These methods are very helpful. I will explain how to use all three of them with examples at the end. The first example, Special Right Triangles, is used only with right triangles. To use this method, you need to have angle measures of 30, 60, and 90, or 45, 45, and 90. There is a "stencil" that goes with
King. {Brutality in Los Angles 7 } Koon along with fellow officers Timothy Wind, Lawrence Powell, and Theodore Brines chased King through downtown Los Angles. King had allegedly committed numerous traffic violations and was thought to be high on PCP. After a hour King pulled his car over and the officers swarmed in to arrest him. King began to struggle then the beating began. Little did the officers know a bystander was filming the whole thing.{Brutality in Los Angles 8} The officers were
What is trigonometry? Well trigonometry, according to the Oxford Dictionary ‘the branch of mathematics dealing with the relations of the sides and angles of triangles and with the relevant functions of any angles.’ Here is a simplified definition of my own: Trigonometry is a division of mathematics involving the study of the relativity of angles and sides of triangles. The word trigonometry originated from the Latin word: trigonometria. Trigonometric ratios are something you would hope to never
Drain Pipes Shape Investigation Introduction A builder has a sheet of plastic measuring 2m by 50cm, which he uses to make drains. The semi-circle is the best shape for a drain. Prove this. I will prove this by comparing its volume to that of other shapes. On older houses there are semi-circular drains but on newer houses there is fancier ones like pentagon shapes. Is this because they are better or is it simply for design? To find the volume of a 3D object I have to find the

I want to find out at which angle is the best to throw the farthest ball. The angles I will test will be a low angle at 15˚, a medium angle at 45˚, and a high angle at 75˚.

Creationism in Public Schools Teaching Creationism in Schools The question as to whether or not creationism should be taught in public schools is a very emotional and complex question. It can be looked at from several different angles, its validity being one of them. Despite the lack of evidence to support the fundamentalist idea of creationism, that in itself is not enough to warrant its exclusion from the curriculum of public schools in the United States. The question is far more involved
simple shapes in geometry because, they come in many different varieties such as, equilateral (3 equal sides; 3 equal angles always 60 degrees), isosceles (only 2 equal sides;2 equal angles), and scalene (no equal sides; no equal angles). Triangles also come in a variety of angles, acute (all angles are less than 90 degrees), right (has a right angle) , and obtuse ( has an angle more than 90 degrees). A triangle is a polygon with three edges and three vertices. As complicated as the information above
