Rotations

Using x and y coordinates, we can rotate shapes on a graph.

90o rotation

  • Shape A has rotated 90o anti-clockwise to become shape B.
    • The x and y coordinates for shape A and B swapped.
    • The x coordinates have changed sign but the y coordinates have not.

180o rotation

  • Shape A has rotated 180o anti-clockwise to become shape B.
    • The x and y coordinates for shape A and B are the same but have changed sign.

270o rotation

  • Shape A has rotated 270o anticlockwise to become shape B.
    • The x and y coordinates for shape A and B swapped.
    • The y coordinates have changed sign but the x coordinates have not.
