Angle Bisector - Deanna Smith

Definition- The (interior) bisector of an angle, also called the internal angle bisector, is the line or line segment that divides the angle into two equal parts.

My definition- a ray or line segment that bisects (splits in half) an angle so that the one angle becomes two congruent angles.

Linear Pair by Andrew Chung


A linear pair of angles is formed when two lines intersect.
Two angles are said to be linear if they are adjacent angles formed by two intersecting lines.
My Definition: Two adjacent angles that are formed by two intersecting lines. They also have two opposite rays.
