According to the definition, the Pythagoras Theorem formula is given as: Hypotenuse2 = Perpendicular2 + Base2 c2 = a2 + b2 The side opposite to the right angle (90) is the longest side (known as Hypotenuse) because the side opposite to the greatest angle is the longest. Since the hypotenuse of a right triangle is the longest side of the triangle, the 90 angle opposite it is also the largest angle of the right triangle. It is also the side opposite from the right angle (90). The perimeter is the sum of the three sides of the triangle and the area can be determined using the following equation: The 30-60-90 refers to the angle measurements in degrees of this type of special right triangle.
