### Theory:

Types of angles of rotation:

1. Full rotation: A $$360°$$ rotation

2. Half rotation: A $$180°$$ rotation

3. Quarter rotation: A $$90°$$ rotation

Look at the following figure.

How will the object look after a $$90$$$$°$$ rotation?

The object takes a quarter rotation and the rotated figure looks like the following.

How will the object look after a $$180$$$$°$$ rotation?

The object takes a half rotation and the rotated figure looks like the following.

How will the object look like after a $$360$$$$°$$ rotation?

The object takes a full rotation and the rotated figure looks exactly like the origin.

The rotated figure will look like this.
