| Acute angle? | Angle less than 90 degres | ||||
| Angle? | formed by two rays connected by the same endpoint. | ||||
| Angle bisector | a ray that divides an angle into two congruent angles. | ||||
| collinear points | lie on the same line | ||||
| congruent angles | angles that have the same measures | ||||
| congruent segments | segments with the same length | ||||
| conjecture | a conclusion reached by using inductive reasoning | ||||
| coordinate | a specific point on a number line or a plane | ||||
| coplanar | points and lines in the same plans | ||||
| counterexample | something that disproves a conjecture | ||||
| inductive reasoning | something that is reached through examples and the process of elimination | ||||
| line | has no length,width,or thickness. it extends without ending in two directions | ||||
| midpoint | a point that divides a segment into two congruent segments | ||||
| obtuse angle | angle more than 90 degrees and less than 180 degress | ||||
| opposite rays | start at the same point but go in opposite directions | ||||
| parrelel lines | coplanar lines across from each other but will never meet | ||||
| perpendicular lines | lines that intersect to form roght angles | ||||
| plane | flat surface that has no thickness. it extends without end in all directions | ||||
| point | no length,width,or thickness, but has a position | ||||
| postulate | an accepted staement of fact | ||||
| ray | part of a line that consists of an initial points and all points on the line that lie on one side of the initial point. | ||||
