WebDraw a picture for each of the following problems. All right triangles have one right (90-degree) angle, and the hypotenuse is the side that is opposite or the right angle, or the longest side of the right triangle. The variable "c" represents the hypotenuse. 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. The Internet is a network, the World Wide Web is what it is 15. The 2+ 2 = 2 The formula is . Doesn't matter how "big" the triangle, those sides will always have the ratio of 1/2.
