Distance around a triangle

You can use the Pythagorean Theorem to find the distance around a right triangle. The equation for this is a2 = b2 + c2. Further through the equation, it is a = square root of b2 +c2. If you know one side of the right triangle is 4 and a second side is 6, the equation would be as follows. a2 = b2 + c2 a = square root of 42 + 62 a = square root of 16 + 36 a = square root of 52 a = 7.211
