Isaiah sketches a model of a skateboard ramp. The model has two surfaces on which to skate, represented by sides AB and AD in the diagram. The steepest side of the model, AB, measures 4 inches. What is the length of the other skating surface, AD?

Consider triangle QRS. The legs each have a length of 10 units. What is the length of the hypotenuse of the triangle?

Consider the incomplete paragraph proof. Given: Isosceles right triangle XYZ (45°-45°-90° triangle) Prove: In a 45°-45°-90° triangle, the hypotenuse is times the length of each leg. Because triangle XYZ is a right triangle, the side lengths must satisfy the Pythagorean theorem, a2 + b2 = c2, which in this isosceles triangle becomes a2 + a2 = c2. By combining like terms, 2a2 = c2. Which final step will prove that the length of the hypotenuse, c, is times the length of each leg?
