The legs of a triangle are called sides A and or B These 2 can be switched around. C on the other hand must be the longest side. A hypotenuse is the longest side of a right triangle, the side opposite the right angle. The length of the hypotenuse of a right triangle can be found using the Pythagorean theorem, which states that the square of the length of the hypotenuse equals the sum of the squares of the lengths of the other two sides. R stands for right A stands for angle and the T stands for triangle together it is called the right angle triangle.
