Final answer:
The angle bisectors of the angles are the lines that divide an angle into two equal parts. Each of the resulting angles is half the measure of the original angle.
Step-by-step explanation:
The angle bisectors of the angles are the lines that divide an angle into two equal parts. When an angle is divided into two equal parts by an angle bisector, each of the two resulting angles is half the measure of the original angle.
For example, if the measure of the original angle is 60 degrees, the measure of each of the resulting angles is 30 degrees.
Angle bisectors are used in various geometric constructions and proofs.
