What is 2D and 3D figure? How to find faces,vertices,edges etc of the shape?

Hi!

Any figure that can be drawn by knowing two dimensions i.e. any two among

*length*,*breadth*and*height*, then such type of figure is called a 2D figure. 2D figures are flat.Example: rectangle, square, parallelogram quadrilateral, pentagon, triangle etc.

Any figure that can be drawn by knowing three dimensions i.e.

*length*,*breadth*and*height*, then such type of figure is called a 3D figure. 3D shapes are solid.Example: cuboid, cube, cone, cylinder, sphere etc.

The polygonal regions in the shapes are called the

**. The faces meet to form line segments which are known as***faces***The edges meet at the points which are known as***edges*.**. To find faces, vertices, edges etc of a shape, you need to visualize a shape and simply count them. For example, the number of faces, edges and vertices of the following shape (a triangular pyramid) are 4, 6 and 4 respectively.***vertices*Hope! You got the concept.

Cheers!
