The problem asks to identify two line segments in the given diagram that are perpendicular to each other. Perpendicular lines intersect at a right angle (90 degrees).

1. Problem Description

The problem asks to identify two line segments in the given diagram that are perpendicular to each other. Perpendicular lines intersect at a right angle (90 degrees).

2. Solution Steps

By examining the provided diagram, we look for line segments that intersect at a right angle. The line segments $TU$ and $QR$ clearly form a right angle where they intersect.

3. Final Answer

The two line segments that are perpendicular are $TU$ and $QR$.
