The problem asks us to identify and mark pairs of line segments based on their geometric properties. Pair A should be marked as parallel, pair B as perpendicular, and pair C as having the same length.

1. Problem Description

The problem asks us to identify and mark pairs of line segments based on their geometric properties. Pair A should be marked as parallel, pair B as perpendicular, and pair C as having the same length.

2. Solution Steps

* Pair A: The two line segments in pair A appear to be parallel, meaning they extend in the same direction and never intersect.

* Pair B: The two line segments in pair B form an angle that appears to be less than 90 degrees. Two lines are perpendicular if they intersect at a right angle (90 degrees). These are not perpendicular.

* Pair C: The two line segments in pair C appear to be the same length by visual inspection.

3. Final Answer

Pair A: Parallel

Pair B: Not Perpendicular

Pair C: Same Length
