The geometric defineetion o a line segment
In geometry, a line segment is a pairt o a line that is boondit bi twa distinct end pynts, an contains every pynt on the line atween its end pynts. Examples o line segments include the sides o a triangle or square. Mair generally, when the end pynts are baith vertices o a polygon, the line segment is either an edge (o that polygon) if thay are adjacent vertices, or itherwise a diagonal. When the end pynts baith lie on a curve such as a circle, a line segment is cried a chord (o that curve).
