R
ΠΝ.
S
T
1. Name four pairs of perpendicular lines.
2. Name four pairs of parallel lines.
3. RPis perpendicular to PN, what is the measure of ZRPN?
4. Given m RMP = 90. What can you conclude about RN and MP? Are they
perpendicular or parallel?​

Answer 1

1. From this given figure, some pairs of perpendicular lines are:

• MP is perpendicular to TO,
• MP is perpendicular to RN,
• PS is perpendicular to MO, and
• NS is perpendicular to MO.

2. From this given figure, some pairs of parallel lines are:

• RM || TP,
• MN || PO,
• RP || MO, and
• MP || MO.

3. The measure of angle RPN is 90°, the measure of any perpendicular angle is 90° .

4. We can conclude that RN and MP are both perpendicular to each other.
