Exercise 18 Page 525

Consider the Lines Perpendicular to a Transversal Theorem

b and c are parallel.
Explanation: See solution.

Practice makes perfect

According to the Lines Perpendicular to a Transversal Theorem, lines that are perpendicular to the same line are parallel to each other. In this case, both b and c are perpendicular to the transversal a. Therefore, we can say with certainty that b and c are parallel.
