Question

1 what is line segment in the figure?

• a median
• an angle bisector
• an altitude
• a perpendicular bisector

Explanation:

An altitude of a triangle is a line segment from a vertex perpendicular to the opposite - side. In the figure, segment $\overline{AE}$ is drawn from vertex $A$ and is perpendicular to side $\overline{DB}$. A median divides a side into two equal parts, an angle - bisector divides an angle into two equal angles, and a perpendicular bisector bisects a side at a right - angle. Here, $\overline{AE}$ is perpendicular to $\overline{DB}$, which is the definition of an altitude.

Answer:

an altitude
