angle | 2 rays that are connected at their endpoints. |
angle bisector | Ray that divides an angle into congruent (=) angles. |

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. |
opposite rays | Starts at the some point... anf go in opposite directions. |
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. |
