**Introduction**

In geometry, we come across two kinds of shapes. These are **plane shapes** and **solid shapes**.

A **plane shape** is two-dimensional in nature. The two dimensions are the **sides** or the **edges** and the **corners** or the **vertices**. The measurements associated with plane shapes are its **area** and **perimeter**.

A solid shape is three-dimensional in nature. We will learn more about these shapes in the next segment.

Learn about the area of plane shapes.

Know about the perimeter of plane shapes.

**Solid Shapes**

A solid shape is also known as a 3D Shape. The three dimensions are the **width**, the **depth**, and the **height**. The measurements associated with solid shapes are its **surface area** and **volume**.

**Examples of solid shapes**

**Cuboid**

**Cube**

**Right circular cylinder**

**Right Circular Cone**

**Sphere**
