- Closed Plane Shapes: Closed shapes are plane figures that have a complete and continuous boundary that forms a closed loop. This means that the shape does not have any openings (holes) or breaks in its boundary. Examples of closed plane shapes include polygons (such as triangles, squares, pentagons), circles, ellipses, etc.

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...
A closed shape is defined as a shape that starts and ends at the same point. In other words, a closed shape does not have an open end. Here are some examples of closed shapes.
Definition of Closed Shapes. A closed shape is a geometric figure in which all the lines and curves form a connected path without any gaps or openings. This means that every point on the shape is connected to at least one other point. Closed shapes enclose a space and have distinct boundaries.
In geometry, a closed shape is a shape that has no open sides or gaps. A closed shape is also called a figure or a form. There are three main types of closed shapes: polygons, circles, and ellipses. Let's take a closer look at each one.
The defining characteristic of a closed figure is that it has no open ends or breaks, meaning that all its points are connected. Some examples of closed plane figures include: Circles: A circle is a closed figure with all points on its boundary equidistant from its center.

Geometric shapes are closed figures created using points, line segments, circles, and curves. Such shapes can be seen everywhere around us. Some of the geometric shape examples are circle, rectangle, triangle, etc. A pizza is circular, whose slices are triangular. Similarly, doors and windows are examples of rectangles.
