How many 2 dimensional shapes are there

Example 3: Identify the 2D shapes from the following. Circle, rectangular box, Rubik's cube, hexagon. Among the given shapes, a circle and a hexagon are 2D shapes because they do not have any thickness or depth. A rectangular box and a Rubik's cube are 3D shapes because they have 3 dimensions, length, width, and height.

A 2D two-dimensional shape can be defined as a plane figure that can be drawn on a flat surface. It has only two dimensions — length and width, with no thickness or depth. Some of the basic 2D shapes are rectangle, pentagon, quadrilateral, circle, triangle, square, octagon, and hexagon.

A flat shape that has two dimensions- length and width, is a 2D shape, whereas, a shape that has three dimensions - length, width, and depth height is a 3D shape. A 2D shape is a flat shape that can be drawn on a plane surface. As the name suggests, it has only two dimensions of length and width without any thickness. While some 2D shapes have sides and vertices, others are made up of curved lines.

There are many different kinds of 2D shapes, like the rectangle, pentagon, quadrilateral, circle, triangle, square, octagon and hexagon. These are flat shapes that can be drawn on a flat surface. The area of a 2D shape is the space occupied by it. Since there are different kinds of 2D shapes like circle, square, rectangle, etc.

The area of 2D shapes is expressed in square units. Teaching 2D shapes is easy if the concept is introduced in the early years. First of all, the names of the basic shapes can be made to learn. Then, the students should be asked to identify the names of the shapes. Another interesting way can be by asking them to spot the shapes around them.

Some commonly seen 2d shapes that can be seen in the house are, the rectangular surface of a notebook rectangle , the circular shape of a clock circle , the circular shape of a pizza, a square-shaped window square. Yes, a circle is a 2D shape because it exists on a plane with no depth. It is a curved shape that has no corners or edges. A quadrilateral is a 2D shape that has four sides. For example, quadrilaterals like squares and rectangles are 2D shapes with 4 sides. Oval is a 2D shape because it exists on a plane and has no depth.

It is a curved figure with no edges or corners. Learn Practice Download. Regular and Irregular 2D Shapes 3. Properties of 2D Shapes 5. Area and Perimeter of 2D Shapes 6. Solved Examples Example 1: Does a rectangle come under the category of 2D shapes? The length of a rectangle is 32 m and the width is 20 m. Find the perimeter of this rectangle. Solution : Yes, a rectangle comes under the category of 2D shapes.
