Holly and Tamar completed the work in the table to determine if a triangle with side lengths of 40, 42, and 58 is a right triangle. Holly’s Work
Tamar’s Work

(40 + 42) squared = 58 squared. 82 squared = 3,364. 6,724 not-equals 3,364.

The triangle is not a right triangle.

42 squared + 40 squared = 58 squared. 1,764 + 1,600 = 3,364. 3,364 = 3,364.

The triangle is a right triangle.
