| Question | Answer |
|---|---|
| Is a line, segment, ray or plane that intersects a segment at it's midpoint. | segment bisector |
| A pair of adjacent angles whose non-common sides are opposite rays | linear pair |
| Are collinear ray with the same endpoints that form a line. | opposite ray |
| Formed by 2 rays with the same endpoint. The common endpoint is the vertex. | angle |

| Are two angles whose sides form 2 pairs of opposite rays. | vertical angles |
| A part of a line that consists of 2 points called endpoints and all the points between them. | segment |
| Segment that have the same length. | congruent segments |
| Angle that equals 90 degrees. | right angle |
| Not in the same plane. | non-coplanar |
| Is the point that the segment in to two congruent halves or the point right in the middle. | midpoint |
| Common point or end point of an angle. | vertex of the angle |
| Are angles that have the same measure. | congruent angles |
| Rays of an angle. | side of an angle |
| Two coplanar angles that have one common side and a common vertex but no common interior. | adjacent angles |
| In the same plane. | coplanar |
| Is a ray that divides an angle into two congruent angles. | angle bisector |
| Is the part of a line that consists of one endpoint and all of the points of the line on one side of the endpoint. | ray |
