An Intro to Points, Lines, Line Segments, and Rays | Geometry | Math with Mr. J

Points00:00:15

A point is a location or position represented by a dot and named with a capital letter. Points do not have size, serving only to indicate a specific position.

Lines00:00:45

A line extends infinitely in both directions, meaning it goes on forever. Arrows at each end of a line, like line XY, visually represent this infinite extension.

Line Segments00:01:38

A line segment has two distinct end points, providing a clear start and stop. Unlike lines, line segments can be measured and do not extend infinitely, such as line segment MN.

Rays00:02:19

A ray has one end point and extends infinitely in only one direction. An example is ray EF, where E is the end point and the ray continues indefinitely through point F.
