Pythagorean Theorem 3 4 5 Right Triangle
This example shows how the pythagorean theorem is true for a right triangle with sides length 3, 4, and 5. The pythagorean theorem equates the squares of the sides of the right triangle together.
Steps

Set up pythagorean theorem and substitute sides of the right triangle.

Evaulate the exponent expressions.

Add the numbers on the left side. Visually this can be respresented as the area of the side squares equals the area of the hypotenuse square.

The theorem holds for a right triangle with sides 3, 4, and 5.
