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.

Definition- When tree points lie on a line, you can say that one point is BETWEEN the other two.
My Definition- When there is a line with three points the middle point is in BETWEEN the two outer points.

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.

Definition: Coplanar points are points that do not lie within the same line or line in a plane
My definition: Coplanar points are points that are not on the same line

Line Segmentby Alex Zhou Definition: a line segment is a part of a line that is bounded by two end points My Definition: a portion of a line that has two ends Diagram:

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.
