## Conic Sections in Taxicab Geometry

explored the conic sections (circle, ellipse, parabola and hyperbola) of taxicab geometry. All pictures, except figure 12, were drawn by me in the program called Geogebra. DEFINING THE PROBLEM Problem given by teacher was: A probe on the surface of planet Mars has a limited amount of fuel left. Because of broken rudder it can only move north- south and east- west. Which points can it reach if it must return back to its base? I solved the problem hence finding a shape of a circle in so-called taxicab geometry

## Geometry: Euclid’s Elements

Most of geometry is based on two main constructions, circles and straight lines. In geometry, there are many different tools used for construction such as the compass, the straightedge, carpenter’s square, and mirrors. (Princeton) A compass is an instrument that is used to help draw circles. The two most well-known compasses are the modern compass and the collapsible compass. The straightedge is a tool that has no curves. It is used to draw straight line when knowing two points. (Princeton) The only

## Significance Of Archimedes's Contribution To Mathematics

areas surround by geometric figure and the slope of the tangent lines of a curve or surface. His contribution in integral calculus helped Sir Isaac Newton to continue the development of calculus. From another work of Archimedes, Measurement of The Circle, recorded the method for approximating the value of pi (π). Pi means ratio between a circle's circumference and its diameter. Based on the theorem of Euclid, Arc...

## Preschool Classroom Observation
