1) 1. Pythagorean theorem can be expressed in an equation __________ where a and b are legs and c is the hypotenuse. a) a2- b2 = c2 b) a2 + b2 = c2 c) a3 + b3 = c3 d) a3- b3 = c3 2) 2. Find the length of the hypotenuse of a right triangle when a = 5 inches b = 12inches . a) 13 inches b) 14 inches c) 15 inches d) 16 inches 3) 3. Which of the following is the length of the hypotenuse with legs 7 and 24 units? a) 23 units b) 24 units c) 25 units d) 26 units 4) 4. A rectangular white screen has a size of 60 inches long and 80 inches wide. What is the diagonal size of the screen? a) 85 inches b) 90 inches c) 95 inches d) 100 inches 5) 5. A gardener wants to place a stepping stones diagonally across a rectangular garden. The garden is 9 meters wide and 12 meters long. The gardener said that the diagonal measures 14 meters. Is his answer correct? a) Yes, because c2 = a2 + b2. So, 92+ 122= 81 + 144; and the result is square root of 225, which is equivalent to 14. b) No, because c2 = a2 + b2 So, 92 + 122 = 81 + 144; and the result is square root of 225, which is equivalent to 15. c) No, c2 = a2 + b2. So, 92 + 122= 81 + 144; and the result is square root of 225, which do not have exact square root. d) Yes because c2 = a2 + b2. So, 92 + 122 = 81 + 144; and the result is square root of 196, which is equivalent to 14.
