- Rotation of Shapes Activity Cut out your shapes
- Slide 28
- Write the coordinate points of the original shape. Translate the shape (x 6, y 3). Record the new coordinates A BC
- Slide 29
- Write the coordinate points of the original shape. Reflect the shape over the x axis. Record the new coordinates A BC
- Slide 30
- Write the coordinate points of the original shape. Reflect the shape over the y axis. Record the new coordinates A BC
- Slide 31
- Write the coordinate points of the original shape. Rotate the shape 90 degrees clockwise. Record the new coordinates A BC
- Slide 32
- Write the coordinate points of the original shape. Rotate the shape 180 degrees clockwise. Record the new coordinates A B C
- Slide 33
- Write the coordinate points of the original shape. Rotate the shape 90 degrees counter clockwise. Record the new coordinates A B C D
