| vertex | a point where 2 rays meet to form an angle |
| ray | sids of an angle |
| line segment | part of a line |
| acute angle | an angle less then 90 degreese |
| obtuse angle | more than 90 degreese less than 180 degreese |

| bisect | splits an angle in to two parts |
| congruent | two angles that have the same measurement |
| perpendicular | lines that intersect to form a right angle |
| Parallel | lines that are the same distance apart at every point |
| collinear | lying on the same line |
