PYTHAGOREAN THEOREM - WORKSHEET
For each triangle find the missing length. Round your answer to the nearest tenth. Then find the area and the perimeter.
For #5-9 c is the hypotenuse of the right triangle ABC with sides a, b, c
5. a = 12 ; b = 5; c =
6. a = 8 ; b = ; c = 10
7. a = 15 ; b = ; c = 17
8. a = ; b = 40 ; c =50
9. a = ; b = 2 ; c = 4
10. Find a third number so that the three numbers form a right triangle:
i) 9 , 41
ii) 13 , 85
11. Ms. Green tells you that a right triangle has a hypotenuse of 13 and a leg of 5. She asks you to find the other leg of the triangle. What is your answer?
