Question

question 3 of 45
in the triangle below, which of the following best describes $overline{ad}$?
a. median
b. altitude
c. angle bisector
d. perpendicular bisector

Explanation:

An angle - bisector divides an angle into two equal angles. Here, $\angle BAC$ is divided into two equal angles ($38^{\circ}$ each) by $\overline{AD}$. A median connects a vertex to the mid - point of the opposite side, an altitude is a perpendicular from a vertex to the opposite side, and a perpendicular bisector bisects a side at a right angle. Since $\overline{AD}$ divides $\angle BAC$ into two equal angles, it is an angle - bisector.

Answer:

C. Angle bisector
