Hint: In geometry, a line or a straight line represents straight objects (i.e., having no curvature) with negligible width and depth.
Any fraction or a part of a line is called a line segment. It has a fixed length.
Recall some objects which are straight and have a fixed length. e.g. a pen.
Complete step-by-step answer:
A straight-line segment looks like this:
Some examples of a line segment, which can be commonly observed in a classroom are:
1. A tube light.: It is straight and has a fixed length of about 3-5 feet.
2. A pen / pencil.: A pen or a pencil are usually straight and are of a fixed length of about 15-20 cm.
3. A scale.: A length measuring instrument, usually 15 cm or 30 cm in length, is a good example of a line segment.
4. The edges of a book / paper / black board.: All these shapes are usually rectangles and their edges are straight line segments.
5. The edges of the classroom.: If the classroom is in the shape of a rectangular box, its edges will be straight.
Note: Lines are described in terms of two points, as only a unique line can pass through them.
From given two points A and B, a line is represented as , a line segment as and a ray as (or , according to its direction).
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.
