Answer:
Line segment- a portion of a line with two endpoints.
Ray- a line with an initial endpoint and then extends infinitely.
Opposite rays- two rays that have the same initial point and extend infinitely in opposite directions in a straight line.
Parallel lines- lines that don't intersect
Collinear- two or more points that lie on the same line.
Coplanar- three or more points that lie in the same plane.
Plane- a flat surface that consists of at least three noncollinear points.
Angle bisector- a ray that divides an angle into two angles that are congruent.
Midpoint- a point that divides a segment into two congruent segments.
Perpendicular lines- two lines that intersect to form a right angle.
