Question

According to the construction shown in the diagram below, what do we call segment $\overline{CD}$?

• A. bisector of $\angle C$
• B. median to side $\overline{AB}$
• C. perpendicular bisector of segment $\overline{AB}$
• D. altitude to side $\overline{AB}$

Answer 1

The correct option is D altitude to side $\overline{AB}$

A perpendicular bisector passes through the midpoint of a side and at right-angles to that side. An altitude passes through a vertex and is at right-angles to the opposite side. A median joins a vertex to the midpoint of the opposite side.
Hence, here the segment $\overline{CD}$ is altitude to side $\overline{AB}$.
