Question: what is the equation to find the base of a triangle?
Answer: a^2 + b^2 = c^2 In this formula, a and b are the lengths of the two legs and c is the length of the hypotenuse. The ^2 signifies that a, b, and c are squared. A number squared is equal to that number multiplied by itself -- for example, 4^2 is equal to 4 times 4, or 16.
