Exercise 21 Page 525

Consider the Lines Perpendicular to a Transversal Theorem.

n ∥ p

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 n and p are perpendicular to the transversal R. Therefore, we can say with certainty that n and p are parallel.

Regarding m and R, it sure looks like they are parallel. However looks can be deceiving. The fact is, we just dont have enough information.
