Who is Pythagoras ?

Phytagoras is a Greek mathematmatician and was also a teacher and a philosopher, He also calculated the earth's circumference and discovered that it was a sphere not a flat. He was known for the Pythagorean theorem ( a2 + b2 = c2 ) , known as the " father of numbers " and was also a vegetarian. Pythagoras was one of the most important people in the world. Although they don't have evidence that Pythagoras excisted he was still an important person in the world.

PROOF ;

PROOF 2 ;

Right Triangle ;
Right Triangle it can also be called " R.A.T " which mean ( right angled triangle ). Side A and B make up the LEGS which is the longest side of the triangle. It doesn't matter where the side A and B goes as long as the hypotenuse is on the right place. The Hypotenuse is the longest side of the triangle. In most triangles something is labeled as " Q & B " Q means theta and B means beta. The right angle on the triangle means 90 degrees.

Square ;
- All sides are equal
- each side are 90 degrees
- all sides equals to 360 degrees

Finding The Sides Of A Square ;
Pythagoras Homework ;

a² + b² = c²
you have to replace the letters into numbers
8² + b² = 10²
now we have to figure out what b equals
b²=(10x10)-(8x8)
b²=100-64
b²=36
we now have to find the square root of 36
b=6
* since thee are two triangles we have to do that twice , which give us b = 12 *
