1. The problem asks to identify which term describes the segment TR in the given triangle. 2. Let's define the terms: - A **median** is a segment from a vertex to the midpoint of the opposite side. - A **perpendicular bisector** is a line that is perpendicular to a side and divides it into two equal parts. - An **altitude** is a segment from a vertex perpendicular to the opposite side. - An **angle bisector** divides an angle into two equal angles. 3. From the description, segment SR has two small red marks indicating it is divided into two equal parts, so R is the midpoint of side SQ. 4. Since TR is drawn from vertex T to point R, which is the midpoint of side SQ, TR is a **median**. Final answer: TR is a median.
