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 5² + 13² = 12²
2. 25 + 169 = 144
3. 194. 144

theorem correctly.
C No. In step 2 she did not square each term
correctly
