Method 1: Solve for the measurements of each side, using the distance formula. If the measurements follow the Pythagorean theorem, then it is a right triangle Method 2: Solve for the slopes of each side, If the product of the slopes of 2 sides = -1, then they are perpendicular (forming a 90degree angle. The sides are AB, BC and AC
