How do you use the pythagoras equation?

Used for right angled triangles where c is the hypothenuse and a and b are the two other sides.

Equation: a² + b² = c²

Label the sides of the triangle before starting.

To find the length of c you do the root of a² + b².

To find the length of either for example b, you rearrange the equation and find the root of c² - a^2.
