4. Points & Lines Line…  drawn with two arrows, one at each end  and is named by two letter points on the line  represented by the figure drawn above the letter name B A Line AB = AB

5. Points & Lines Segment…  drawn with two endpoints, one at each end  and is named by the endpoints  represented by the figure drawn above the letter name D C Segment CD = CD

6. Points & Lines Ray…  drawn with one endpoint and one arrow  and is named by two points on the ray  represented by the figure drawn above the letter name  when you name a ray, you name the endpoint first K J Ray KJ = KJ
