Question

1. if a ____ bisects an angle of a triangle, then it divides the opposite side into segments whose lengths are proportional to the lengths of the other 2 sides.

options: segment, line, ray, plane

Explanation:

According to the Angle Bisector Theorem, an angle bisector of a triangle divides the opposite side into segments proportional to the adjacent sides. A ray is the geometric figure that bisects the angle (as an angle bisector is a ray starting from the vertex of the angle).

Answer:

ray
