Question

5.Andrew claims that a wooden bookend in the shape of a 45°- 45°- 90° right triangle has side lengths of 9 in., 9 in., and 11 in. Is he correct? If so, show the work and if not, show why not.

Answer 1

If it is a right angled triangle, then 9^2 + 9^2 should = 11^2

9^2 = 81

81 x 2 = 162

11^2 = 121

Answer 2

162 is not equal to 121, therefore he is wrong
