v. t. e. In geometry, a line segment is a part of a straight line that is bounded by two distinct end points, and contains every point on the line that is between its endpoints. It is a special case of an arc, with zero curvature. The length of a line segment is given by the Euclidean distance between its endpoints.

In geometry, a closed shape can be defined as an enclosed shape or figure whose line segments and/or curves are connected or meet end to end. Closed shapes start and end at the same point. The least number of sides required to make a closed shape is 3, which forms a polygon named a triangle.
The following table mentions all the differences between open and closed shapes based on their definitions. Let’s have a look:
The least number of sides a closed shape can have is 3, which is a polygon named triangle. 1. A triangle is a three-sided closed shape polygon having three vertices. 1. A circle is a closed shape with one face and no sides or vertices. 1. A quadrilateral is a four-sided closed shape having four vertices. Square, rectangle, rhombus, parallelogram, a...
Example 1. How many sides does this shape have? Is the shape closed or open? Solution: First, we count the number of straight lines in the shape. There are eight straight lines connected to each other, making an octagon. As this octagon’s outline may be traced without any gaps, it is a closed shape. Example 2. Are straight lines necessary to make c...
Aug 12, 2022 · Geometric shapes, also called figures, are an important part of the study of geometry. The triangle is one of the basic shapes in geometry. It is the simplest shape within a classification of shapes called polygons. All triangles have three sides and three angles, but they come in many different shapes and sizes.
Examples of Line Segments. The most common examples we can see in 2d geometry where all the polygons are made up of line segments. A triangle is made up of three line segments joined end to end. A square is made up of four-line segments. A pentagon is made up of five-line segments.
- A line segment is a part of line that has two distinct endpoints. These endpoints are definite in nature.
- A line segment has endpoints whereas a line extends infinitely at both ends.
- A ray has only one endpoint whereas a line segment has two endpoints. One end of the ray extends infinitely but the endpoints of a line segment are...
- A line segment is denoted by a Bar (-) on the top of its notation, say AB.
- A ruler, a scale, a stick, a boundary line, etc., are examples of the line segment
Nov 26, 2020 · Line segments. A line segment is a piece of a line that connects two points. The points at the end of the line segment are called endpoints. You name a line segment by using its endpoints. The symbol for a line segment is the letter name of each of the endpoints with a line over the top. A drawing of a line segment has two points at the ends.
Closed shapes. The line segments or curves forming a closed shape are continuous, meaning there is no break. The lines/curves must also form a closed region to be considered a closed shape: Open shapes. The segments or curves of an open shape are not always connected. At least one endpoint of one side is not connected to the rest: 2D shapes

Feb 8, 2020 · Definition: A polygon is a closed figure where the sides are all line segments. Each side must intersect exactly two others sides but only at their endpoints. The sides must be noncollinear and have a common endpoint. Note: A circle is not a polygon as it does not have straight sides.
