Pythagorean Theorem

# Pythagorean Theorem

Pythagorean Theorem:
In a right angled triangle, with sides (legs) a and b, and hypotenuse c, then

c² = a²+b².

The square of the hypotenuse is the sum of the squares of the legs.

A "3,4,5" triangle has a right angle in it, so the formula should work.

 52=32+42 25=9+16 25=25 Yes, it works!!!

Apply the Pythagorean Theorem: If you know any two of the sides in a right triangle, you can find the dimensions for the missing side using the Pythagorean Theorem.

In a right triangle you know the hypotenuse is 15 units long and one leg is 12 units long.

Calculate the other leg:

 Solution:
