In mathematics, endpoints are crucial concepts when referring to line segments or intervals.

An endpoint is essentially a point that marks the end of a segment or the beginning of a segment. It is the point where a line segment starts or ends.

To better understand endpoints, let’s consider a line segment AB. Here, A and B are the endpoints of the segment, indicating the starting and ending positions of the line segment. The endpoints give clear definitions to the boundaries of the segment.

It’s important to note that endpoints represent single points in space, and they can be identified using coordinates in various coordinate systems. For example, in a two-dimensional Cartesian coordinate system, an endpoint can be represented by an (x, y) coordinate. In three-dimensional space, it can be denoted by (x, y, z). These coordinates help us locate and distinguish one endpoint from another.

Additionally, if we consider an interval on the number line, endpoints become significant to define the range. For example, in the interval [a, b], ‘a’ represents the left endpoint, and ‘b’ represents the right endpoint. The interval includes all values between a and b, including a and b themselves.

Endpoints play a vital role in mathematics as they provide precise definitions to segments and intervals, allowing us to analyze and solve problems involving geometric figures, functions, and more.
