A 2D shape has no thickness or depth. Example 3: Match the 2D shape with its property. (i) It has no corners and edges. (ii) It has one pair of opposite sides parallel to each other while the other two sides are non-parallel. (iii) It is a closed figure with three straight sides. (iv) Each of its angles measures 90°.
2D Shapes. A 2D shape is a flat shape that has only two dimensions - length and width, with no thickness or depth, that is the reason why it is called a two-dimensional shape. For example, a sheet of paper is two-dimensional in shape. It consists of a length and a width but does not have any depth or height. Some common 2D shapes are squares ...
Regular Polygons. A polygon is a 2D shape with straight sides. To be a regular polygon all the sides and angles must be the same: Triangle - 3 Sides. Square - 4 Sides. Pentagon - 5 Sides. Hexagon - 6 sides. Heptagon - 7 Sides. Octagon - 8 Sides.
Geometrical shapes are all around us. They make up the form and structure of every two-dimensional (2D) and three-dimensional (3D) object. In mathematics—namely geometry—and in real life, geometric shapes are two or three-dimensional figures that can be recognized and categorized based on a specific outline/boundary and other attributes including curves, lines, and angles.
The basic types of 2d shapes are a circle, triangle, square, rectangle, pentagon, quadrilateral, hexagon, octagon, etc. Apart from the circle, all the shapes are considered as polygons, which have sides. A polygon which has all the sides and angles as equal is called a regular polygon. Including the circle, an ellipse is also a non-polygon shape.

- A cylinder is a 3d shape that has two parallel bases and lateral sides. The two bases are circular in shape.
- 2d shapes do not have height or thickness but 3d shapes have height.
- A pentagon is a 2d shape that has five sides.
- A line is a one-dimensional shape.
- There are many examples in real-life we can see for 2d shapes, such as: A ring (Circle) A rectangular plot A square shape plate Tiles A piece...
Facts about Plane Shapes. 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.

Identify shapes as two-dimensional (lying in a plane, “flat”) or three-dimensional (“solid”). Grade 1: Geometry (1.G.A.2) Compose two-dimensional shapes (rectangles, squares, trapezoids, triangles, half circles, and quarter-circles) or three-dimensional shapes (cubes, right rectangular prisms, right circular cones, and right circular ...
