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.

Congruent segments:Andrew Jurewicz

Definition: two lines that have the same length
My definition: two or more lines that share a common measure and length. You can find the length by using the distance formula or just counting when the line is either horizontal or vertical on the cooridante plane.
