- 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.

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...
The worksheet challenges young mathematicians to hone their math skills by solving a set of problems on identifying open and closed shapes. Help your student become proficient in geometry with this worksheet.
Open and Closed Shapes Practice identifying open and closed shapes.
Looking at Shapes: Open or Closed? What makes a shape a shape? Geometry students learn to recognize shapes as they look at a variety of forms and determine if they are open or closed. Through repeat practice, children familiarize themselves with 2D shapes and their properties.
Grade 1 - Geometry. Standard 1.G.A.1 - Determine whether a two dimensional shape is open or closed. Included Skills: 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.
