** Definition of Rotation**

- A Rotation is a transformation that turns a figure about a fixed point.

**More about Rotation**

- Rotation is also called as turn.

- The fixed point around which a figure is rotated is called as centre of rotation.

**Example of Rotation**

- Figure B is a rotation of 180° of Figure A.

**Solved Example on Rotation**

Identify the figures that represent a rotation.

Choices:

A. Figure 1 and Figure 2

B. Figure 1, Figure 2, and Figure 3

C. Figure 3 and Figure 2

D. Figure 1 and Figure 3

Correct Answer: A

Solution:

Step 1:A Rotation is a transformation that turns a figure about a fixed point called the center of rotation.

Step 2:Here, in Figure 1 and Figure 2, the figures are turned about a fixed point called the center of rotation.

Step 3:So, Figure 1 and Figure 2 represent rotation.
