Introduction
In previous year you have learnt about plane shapes and solid shapes. Plane shapes can only be measured in 2 directions breadth and length. They do not have depth or height. They have one flat surface, sides, angles and vertices. They are called 2dimensional figures. Examples: Square, Rectangle, circle, triangle.
Â
3dimensional shapes have depth. They can be measured in 3 directions, breadth, length and height. They have more than one face and many edges. 3dimensional shapes have many more angles and vertices than 2dimensional shapes.
Â
Example :Â Cube, cuboid, cylinder, prism, pyramid etc.
