Question: what is the formula for a 90 degree triangle?
Answer: The longest side of a right triangle is called the hypotenuse, and it is the side that is opposite the 90 degree angle. If the length of the hypotenuse is labeled c , and the lengths of the other sides are labeled a and b , the Pythagorean Theorem states that a2+b2=c2 a 2 + b 2 = c 2 .
