Did Bryn come to the correct conclusion? If not explain

her error.

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 + 13° = 12

2. 25 + 169 = 144

3. 194 + 144

Conclusion: Not a right triangle

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.

O Yes, Bryn came to the correct conclusion.
