2 Part Five: Pythagorean Theorem/Altitude Rule/Leg Rule 1) The lengths of the sides of a triangle are 6, 2.5, and 15. Is this a right triangle? 2) In the diagram below of right triangle ABC, altitude is drawn to hypotenuse, AC=16, and CD=7. What is the length of? (1) (2) (3) (4) 1 3) The lengths of the sides of a triangle are.9, 4, and 4.1. Is this a right triangle? 4) Find the measure of the diagonal of a rectangle whose sides are 25 and 50, in simplest radical form. 5) In the diagram below of right triangle ACB, altitude is drawn to hypotenuse. If AB = 36 and AC = 12, what is the length of? (1) 32 (2) 6 (3) 3 (4) 4 6) Firefighters have a 29 foot extension ladder in order to reach 25 feet up the building. How far away from the building should the ladder be placed? Round to the nearest tenth. Include a diagram with your answer. 7) What is the exact length of the diagonal of a square with a perimeter of 60 inches? (in simplest radical form). 8) Given the following diagram, find the length of a, b, and c. Round answers to the nearest tenth. 9) Use the diagram below to find the value of x. Answer must be in simplest radical form. 10) Two joggers run 8 miles north and 5 miles west. What is the shortest distance, to the nearest mile, they must travel to return to the starting point? 11) In right triangle JKL, <K is a right angle. Altitude KH intersects the hypotenuse JL in such a way JH is 21 more than the length of HL. a. If HL = x, then find the value of JH in terms of x. b. If the altitude, KH = 10, then what is the value of HL.
