Solution to Each Rotation:

First Diagram

1. Shape A to B:
   • The shape has been rotated 90° clockwise.
   • Center of rotation: (0, 0).

Second Diagram

2. Shape A to B:
   • The shape has been rotated 90° counterclockwise.
   • Center of rotation: (0, 0).

Third Diagram

3. Shape A to B:
   • The shape has been rotated 180°.
   • Center of rotation: (0, 0).

Answers to Fill:

• First Diagram:
  • Centre: (0, 0)
  • Angle: 90c
• Second Diagram:
  • Centre: (0, 0)
  • Angle: 90a
• Third Diagram:
  • Centre: (0, 0)
  • Angle: 180
