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.

segment

line

ray

plane

Explanation:

The Angle Bisector Theorem states that if a segment bisects an angle of a triangle, then it divides the opposite side into segments proportional to the adjacent sides. A line is infinite, a ray has one endpoint and is infinite in one direction, and a plane is a two - dimensional flat surface. A segment has two endpoints and is the correct geometric object for this theorem.

Answer:

segment
