Exercise 27 Page 447

What do we call angles that are adjacent and on a straight line?

True, see solution.

Practice makes perfect

The given equation, m∠ 2+m ∠ 3=180^(∘), tells us that the measures of ∠ 2 and ∠ 3 sum to 180^(∘). From the figure, we can see that these angles are adjacent on a straight line. They form a linear pair.

By the Linear Pair Postulate, they are supplementary. All supplementary angles add to 180^(∘), so the statement is true!
