To understand how different shapes rotate, let's break it down into simple parts:

1. Centre of Rotation: This is the point where a shape spins around. Common places for this point are:

   • A corner of the shape (like a triangle).
   • The middle of the shape (like a rectangle).

2. Angle of Rotation: This tells us how far a shape has turned. We measure it in degrees (°). Here are some common angles:

   • $90°$: This is a quarter turn.
   • $180°$: This is a half turn.
   • $270°$: This is a three-quarter turn.
   • $360°$: This is a full turn.

3. Direction of Rotation: There are two main ways a shape can turn:

   • Clockwise (CW): This means it turns to the right.
   • Counterclockwise (CCW): This means it turns to the left.

Getting to know these ideas helps us picture how shapes look after they spin. This is really important when learning about geometry in Year 8 math!
