Question

Bryn checked the measures of the stairs to make sure they formed a right triangle. The measures of the steps were 5 in., 13 in., and 12 in. Bryn’s work is shown below: 1. 5 squared + 13 squared = 12 squared. 2. 25 + 169 = 144. 3. 194 not-equals 144. Conclusion: Not a right triangle. Did Bryn come to the correct conclusion? If not explain her error. No. In step 1 she did not apply the Pythagorean theorem correctly. No. In step 2 she did not square each term correctly No. She should have used the outcome from step 3 to conclude that the triangle is a right triangle. Yes, Bryn came to the correct conclusion.
