The Pythagorean Theorem c a b
This is a right triangle:
We call it a right triangle because it contains a right angle.
The measure of a right angle is 90o
The little square in a triangle tells you it is a right angle.
About 2,500 years ago, a Greek mathematician named Pythagorus discovered a special relationship between the sides of right triangles.
Pythagorus realized that if you have a right triangle, 3 4 5
and you square the lengths of the two sides that make up the right angle, 3 4 5
and add them together, 3 4 5
you get the same number you would get by squaring the other side. 3 4 5
Is that correct? ? ?
It is. And it is true for any right triangle. 8 6 10
