Beyond Pythagoras Investigation

In this investigation, I am trying to find the rules and patterns for

right-angled triangles. Each length of the right-angle triangle is

going to be a positive integer, and the shortest length is going to be

an odd number.

Below is a typical type of a Pythagoras triple equation:

[IMAGE]

Formula:a² + b² = c²

3² + 4² = 5²

9 + 16 = 25

In this equation, the first step I took was to put the numbers instead

of the letters. Once I did that I squared all the numbers, and when I

add a² + b² it equaled to c². Incase one of the numbers was missing on

the triangle; I would replace that as x², and carry out the formula as

a normal algebraic expression. When you look at the numbers at first

they don't add up. If you do 3 + 4 it does not equal to 5, but once

the numbers are squared they add up.

This is the second type of a Pythagoras triple equation:

[IMAGE]

In this example the exact same procedure was done. I put all the

numbers instead of the formula and worked it out. The first step I

took was to square all the numbers. To check that my work was correct

I added a² + b² to get c². So far both example that were shown satisfy

the condition because when I added a² + b² I got c². One thing I found

in common between both of the right-angled triangle was that the

hypotenuse and the second biggest number had a one number difference.

This is the third type of Pythagoras triple:

[IMAGE]

On this third example, the Pythagoras triple worked because once 'a'

and b were squared, and when added then they equal to c². Just like

the other two examples, I used the same method to solve the equation

and also the check it. Also, in this example there are similar things

between the hypotenuse and the second biggest side, just like in the

Pythagoras also developed the Pythagorean brotherhood. This was religious in nature, however it formulated principals that influenced the thoughts of Plato and Aristotle, and contributed to the development of mathematics and Western rational philosophy. Pythagoras not only developed the theorem of A2+B2=C2, but he was also the first to create the music scale of today. Unfortunately none of Pythagoras’s writings from this development time have survived to present day.

- Explains that pythagoras studied the properties of numbers like mathematicians of today would. however, he gave numbers a personality. modern mathematics has deliberately eliminated these personality factors from its presence.
- Explains that pythagoras' famous geometry theorem was known to the babylonians 1000 years earlier, but he may have been the first to prove it.
- Opines that pythagoras was one of the world's greatest men, but none of his writings are available. his followers had the good sense to record lots of it for him.
