Lesson 16.1 Points & Lines

Math Vocabulary point – a location in space line – made up of many points and extends endlessly in both directions segment – part of a line; has two endpoints ray – part of a line; has one endpoint and extends endlessly in one direction

Points & Lines Point…  can be any location in space  and is named or represented by a letter А C

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

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

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
