alleryThe angle bisector theorem compares a side's parts with what?
AThe other two sides
BThe three angles
CThe incircle radius
DThe triangle area
Answer & Solution
Correct answer: A. The other two sides
1. A bisector of one angle cuts the opposite side into two parts.
2. The theorem sets the ratio of those parts equal to the ratio of the other two sides.
3. Angles, radii and areas are not compared here.
