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.
