## Course Overview

The Pythagorean equation relates the sides of a right triangle in a simple way, so that if the lengths of any two sides are known the length of the third side can be found

**Pythagorean Theorem**

In a right triangle with hypotenuse c and the smaller sides**a**and**b**,**c**^{2}=a^{2}+b^{2}

You can visualize a right triangle with squares on each side. Area of the square is square of its side length.

The area of the square on the hypotenuse is equal to the sum of the areas of the squares on the legs.

A right triangle has right angle (90° )as one of its angles. The side opposite to the right angle is called hypotenuse and the other two sides are called legs. Hypotenuse is the longest sides of the right triangle.
