| line segment | a part of a line that has two end points |
| ray | a part of a line that one end of a piont extends to infinity |
| line | a group of point on a straight that extends to infinty |
| point | a geometric element that has position but no extension |
| parallel lines | are line that don't intersect |
| intersecting | is when lines cross and the point will meet in the center |
| perpendicular | when two lines are perpedicular if the product of their slopes is also the two intersecting lines form right angle |
| angle | when two ray's having a comman end point |
