Exercise 46 Page 510

Recall that a rectangle has four right angles.

Tamika is correct, Parker is not, see solution.

Practice makes perfect

Let's begin with recalling that in a rectangle there are four right angles. Therefore, if we want to arrange two congruent triangles to make a rectangle, they need to have one right angle, which means Tamika is right.

In the case of arranging acute triangles, we will not be able to have four right angles. This means that Parker is not correct in his reasoning.
