LINE SEGMENT : 

LINE SEGMENT A LINE SEGMENT is part of a ray or line. It has two endpoints Line Segment Line Endpoints

VERTEX : 

VERTEX Two rays or lines that have the same endpoint make a VERTEX/angle VERTEX/angles are measured in “degrees” The Corners of a square are its vertex/angles The vertex is the point where the two lines meet on an angle
