Pythagoras was a Greek philosopher who made important developments in mathematics, astronomy, and the theory of music. The theorem now known as Pythagoras's theorem was known to the Babylonians 1000 years earlier but he may have been the first to prove it.

The Side A and Side B can be two different numbers but they both have to equal 90 degrees. These two sides are also called legs for the triangle. Once these 2 angles are added they are called Complementary Angles. There are also angles that are 180 degrees and make a straight line. This is called Supplementary.

In this picture there are two triangles that make one rectangle.

Two triangles can also be used to make 1 square or other

quadrilateral.

Question Example -

a²+b²=c² - Theorem

16²+12²=c²

(16x16)+(12x12)=c²

256 + 144 square root of 400 20=c

To make sure that your answer is right look

at the triangle and check the side or the length

your working on and see if the other sides and

shorter or longer.
