1. Warm up
What type of transformation is shown? Write the algebraic representation.
Write the coordinates of the original triangle after reflection over
X- axis:
Y-axis:

3. The distance from the center to any point on the shape stays the same.
Rotations
A turn around a center.
The distance from the center to any point on the shape stays the same.

4. Rotational Symmetry
Any figure that can be turned or rotated less than 360° about a fixed point so that the figure looks exactly as it does in its original position.

6. Rotate 90 Clockwise about the Origin (Same as 270 Counterclockwise)
Change the sign of x and switch the order

7. Rotate 90° clockwise about the origin

8. Rotate 90° clockwise about the origin

9. Rotate 180 clockwise about the origin
ONLY Change the signs

10. Rotate 180° clockwise about the origin

11. Rotate 180° about the origin

12. Rotate 270 clockwise about the Origin
Change the sign of y and switch the order

13. Rotate 270° clockwise about the origin

14. Rotate 270° clockwise about the origin

15. Rotation 180 degrees about the origin

16. Rotation 270 degrees about the origin
Or 90 degree counter clockwise about the origin

17. Rotation 90 degrees about the origin

18. Write down the coordinates of the image after
