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...

2 All three shapes in the image are closed shapes because they have no openings or gaps
Standard 1.G.A.1 - Determine whether a two dimensional shape is open or closed. Distinguish between defining attributes (e.g., triangles are closed and three-sided) versus non-defining attributes (e.g., color, orientation, overall size); build and draw shapes to possess defining attributes. If you notice any problems, please let us know.
Understanding the properties discussed above is crucial in determining the characteristics of closed shapes and solving problems related to them. Examples and Real-World Applications. To further clarify the concepts of closed shapes, let's consider a few examples and explore their real-world applications. Example 1: Rectangle
