1. Midpoint
A line segment is the point halfway between the endpoint of a segment.
2. Ray
• -A part of a line
• -Only has 1 endpoint
• -Extends indefinitely in one direction.
3. Opposite Rays
Two rays going in opposite directions.
4. Angles
• -Formed by 2 noncollinear rays
• -2 rays = sides
5. Congruent Angles
• -Angles that have the same measure.
• -Arcs on the figures indicate which are congruent.
6. Bisector
A ray that divides an angle into 2 congruent angles.
2 angles that lie in the same plane, have a common vertex, and a common side but does not share any interior points.
8. Verticle Angles
2 angles that are not adjecent and are formend when 2 lines intersect (cross).
9. Linear Pair
A pair of adjacent angles whose nocommon sides are opposite

*A linear pair will always sum up to 180°.
10. Complementary
Any 2 angles
11. Supplementary Angles
2 angles whose measure adds up to 180°.
12. Perpendicular Angle
Lines that intersect to form right angles.
