Closed Shapes in Geometry. The least number of sides a closed shape can have is 3, which is a polygon named triangle. A triangle is a three-sided closed shape polygon having three vertices. A circle is a closed shape with one face and no sides or vertices. A quadrilateral is a four-sided closed shape having four vertices.
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. Closed shapes made up of straight lines are known as polygons.
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 ...
A closed object is also called a solid. Examples of closed objects include spheres, cubes, and cylinders. Functions and Graphs. 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.
Such bounded geometric shapes like polygons are called closed figures. A boundary of a closed figure is not only made of line segments but also of curves. Hence, a closed figure can be defined as any geometric shape which starts and ends at the same point to form a boundary by line segments or by curves. Open Shapes. Open figures are incomplete ...

Plane shapes, also known as 2D shapes, are flat figures that exist in a two-dimensional space, with length and width but no depth. A polygon is a closed plane figure with straight sides. Examples of polygons include triangles, quadrilaterals, pentagons, hexagons, and so on. Circles are another type of plane shape.

Shapes are closed shapes that are created by joining lines together. Closed shapes made of four straight lines are called quadrilateral shapes. Here is a list of shapes with real-world examples. Circle: A circle is a closed shape. It is categorized as a two-dimensional geometric shape that is round in structure. It does not have any lines or ...
