the formula?

it states that

In mathematics, the Pythagorean theorem, also known as Pythagoras' theorem, is a relation in Euclidean geometry among the three sides of a right triangle. It states that the square of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides.

a²+b²=c²

a² + b² = c²

To find b, do sqrt(c² - a²)

To find c, do sqrt(a² + b²)

Hope this helps!
