| angle | 2 rays that are connected at their endpoints. |
| angle bisector | Ray that divides an angle into congruent (=) angles. |
| collinear points | Points that lie on the same line are collinear points. |
| congruent angles | Angles with the same measures. |
| congruent segments | 2 segments with the same length. |
| conjecture | A conclusion reached by using inductive reasoning. |
| coordinate | 2 axis meet at the origin. |
| coplanar | points and lines in the same plane. |
| counterexample | A perticular example or instance of the statement that makes the statement false. |
| inductive reasoning | Is a type of reasoning that reaches conclusions based on a pattern of specitic examples or pasr events. |
| line | Has length, but no width or thickness. It extends without end in 2 directions |
| midpoint | A point that divides a segment into two congruent segments. |
| obtuse angle | More than 90 degrees. |

| parallel lines | Coplanar lines that do not intersect. |
| perpendicular lines | Lines that intersect to form right angles. |
| plane | A flat surface that has no thickness. It extends without end in all directions. |
| point | Has no length, width, or thickness, but has position. |
