Question Analysis

This question focuses on identifying the type of line segment in the triangle, based on knowledge of mid - segments, angle bisectors, and perpendicular bisectors.

Key Concept Explanation

Mid - segment: Connects the midpoints of two sides of a triangle.

Angle bisector: Divides an angle of a triangle into two equal - measure angles.

Perpendicular bisector: Is perpendicular to a side of a triangle and bisects that side.

Step - by - Step Solution

1. Observe the markings on the triangle. The red arcs at and indicate that these two angles are equal.

2. Since divides into two equal - measure angles, it meets the definition of an angle bisector.

Option Analysis

A.Mid - segment: Incorrect. There is no indication that
