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.

Feb 5, 2024 · Properties of Plane Figures. Plane figures have many different properties that can be used to classify them and solve problems involving them. Some of the most important properties of plane figures include: Sides: Plane figures may possess any number of sides ranging from three to infinite. Polygons have three or more sides, while circles have ...
Nov 1, 2021 · A plane in geometry is a flat surface that extends up to infinity in all directions. 2D shapes will be a plane figure which can be drawn on a plane surface or a paper piece. Every 2D shape will have parameters like perimeter and area. Types of Plane Figures. The following are the different types of plane figures. The plane figures are: Circle ...
A shape can be defined as the boundary or outline of an object. A plane shape is a two-dimensional closed figure that has no thickness. Learn about shapes, the different types of shapes, circle, rectangle, square, oval, triangles, and polygons and their properties.

This article is about the explanation of different types of 2D Shapes like Circle, Triangle, Square etc., along with their properties and comparison between 2D & 3D Shapes.
In maths, 2d shapes are defined as plane figures that can be drawn on a flat surface or piece of paper. They have various parameters such as area and perimeter. Some contain sides and corners while others have curved boundaries.
The basic types of 2d shapes include circle, triangle, square, rectangle, pentagon, octagon etc. Polygons with equal sides and angles are called regular polyggons while the circle is a non-polygon shape with a curved boundary.
A circle is a closed figure in which all points in the plane are equidistant from the center point; it has radius length from center to outer line; examples include wheels and pizzas.
A triangle is three-sided polygon (2D shape) with three edges & vertices; sum of its angles = 180°; example - pyramids .
A square is four-sided polygon (2D shape) whose sides & angles are equal in length & 90° respectively ; diagonals bisect each other at 90° ; examples - wall or table .
A rectangle has 4 sides where opposite sides are equal & parallel to each other with all angles being 90° ; examples - brick , TV , cardboard .
A pentagon is five sided polygon (2D shape) that can be regular/irregular ; interior angle = 108° for regular pentagons ; exterior angle = 72° for regular pentagons ; 5 diagonals exist .
A plane figure is a flat shape. It does not have depth or thickness. Plane figures only have two dimensions (length and width). Thus, they are also known as 2D figures or two-dimensional shapes. Some common examples of geometric plane figures are squares, rectangles, circles, triangles, etc. A plane figure lies all within a single plane.
