Examples of a quadrilateral are square, rectangle, rhombus, parallelogram, trapezium, etc. A pentagon is a closed shape with 5 sides and 5 vertices. A hexagon is a closed shape with 6 sides and 6 vertices. There are many other closed shapes in geometry apart from the ones that are mentioned above, for example, heptagon, octagon, decagon, oval, 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...
Example 1: Identify whether the following shapes are open or closed shapes. Solution: In the image, there are both open and closed shapes. The first two shapes are open as in both shapes, the starting and end point are not the same. Hence, they are open shapes. The next three shapes are examples of different geometrical shapes such as heptagon ...
Polygons. A polygon is a closed shape with straight sides. The word "polygon" comes from the Greek words "poly," meaning "many," and "gonia," meaning "angle." Polygons are classified based on the number of sides they have. Polygons can be further divided into regular and irregular polygons:
They are also called freeform shapes or organic shapes. For example, the shape of a tree is irregular or organic. In plane geometry, the two-dimensional shapes are flat shapes and closed figures such as circles, squares, rectangles, rhombus, etc. In solid geometry, the three-dimensional shapes are cube, cuboid, cone, sphere and cylinder. We can ...

A closed plane figure, also known as a closed shape or a closed curve, refers to a geometric shape that is composed of a finite set of connected line segments or curves in a two-dimensional plane. The defining characteristic of a closed figure is that it has no open ends or breaks, meaning that all its points are connected.

Nov 4, 2024 · This is an example of a closed shape. Then they can have the student make a design using the string where the two ends do not connect. This is an open shape. This hands-on activity is a great way to build a conceptual understanding of open and closed shapes. Geometric shapes. Geometric shapes are closed shapes that have measurable attributes.
