Question

A line segment has how many end points?
A. One
B. Two
C. Three
D. Four

Answer 1

Hint: In geometry, any fraction or a part of a line is called a line segment. It has a fixed length.
A line or a straight line represents straight objects (i.e., having no curvature) with negligible width and depth.
Recall some objects which are straight and have a fixed length. e.g. a pen.

Complete step-by-step answer:
A line segment is a part of a line that is bounded by two distinct endpoints, and contains every point on the line between its endpoints.

A closed line segment includes both endpoints, while an open line segment excludes both endpoints; a half-open line segment includes exactly one of the endpoints.
The correct answer is B. Two.

Note: Lines are described in terms of two points, as only a unique line can pass through them. A line has no end points, a ray has one endpoint and a line segment has two endpoints. From given two points A and B, a line is represented as $\overleftrightarrow{AB}$ , a line segment as $\overline{AB}$ and a ray as $\overrightarrow{AB}$ (or $\overrightarrow{BA}$ , according to its direction). It is illustrated in the following graphical representation:

In general, a line can be extended infinitely in both the directions, whereas a ray can be extended infinitely in the direction of its arrow. But a line segment is of a fixed length, equal to the distance between the two end points.
