look at the diagram.
which term describes \\(\overline{qs}\\)?
median
perpendicular bisector
altitude
angle bisector

Explanation:

Step1: Recall definitions

• Median: A segment from a vertex to the midpoint of the opposite side.
• Perpendicular bisector: A line that is perpendicular to a segment and bisects it (hits at midpoint).
• Altitude: A segment from a vertex perpendicular to the opposite side (or its extension).
• Angle bisector: A segment that divides an angle into two equal parts.

Step2: Analyze the diagram

In the diagram, $\overline{QS}$ is perpendicular to $\overline{RT}$ (right angle symbol at $S$), and it connects vertex $Q$ to side $RT$. It doesn't need to bisect $RT$ (no midpoint indication) or bisect an angle (no angle division shown). So it's an altitude, as it's a perpendicular segment from a vertex to the opposite side.

Answer:

altitude
