# Worksheet: Parallel, Perpendicular, and Intersecting Lines

In this worksheet, we will practice describing the relations between straight lines, line segments, and rays as parallel, intersecting, or perpendicular and identifying congruent line segments.

**Q1: **

Which of the following correctly defines perpendicular lines?

- ATwo lines are said to be perpendicular if they meet at a reflex angle.
- BTwo lines are said to be perpendicular if they never intersect however far they are extended.
- CTwo lines are said to be perpendicular if they meet at an acute angle.
- DTwo lines are said to be perpendicular if they meet at an obtuse angle.
- ETwo lines are said to be perpendicular if they meet at right angles.
