Segment

In geometry, a segment is a straight line that connects two points on a plane, and includes all points between them. Unlike a line that extends infinitely in both directions, a segment has a definite start and end. It’s like a piece of string or a segment of a road between two cities. Segments are fundamental in figuring out distances, shapes, and other properties of geometric figures. They are used to measure lengths and define the boundaries of shapes such as triangles, rectangles, and polygons.
