Pythagorean Theorem

Quick math review on some geometry, pythagorean theorem.

In a right triangle the square of the hypotenuse of a right triangle is equal to the sum of the square root of the other two sides.

c^2 = b^2 + a ^2 or c = sqrtt of (b^2 + a^2) where c = the hypotenuse (longest side).

Example)

What is the hypotenuse of a triangle with one side at 1.5 meters and the other at 2 meters?

c = sqrt (1.5^2 + 2^2) = sqrt (2.25 + 4) = sqrt (6.25) = 2.5
