Find the images of the triangle DCE under the following transformations:
1. Translation given by the vector u.
2. Line reflection given by the line a.
3. Rotation 90° clockwise about the point H
4. Glide reflection given by the line a and vector u.
Explain how you use the square grid to find to find the images. You may print the applet image (applet menu > Print preview) to work on it.
Make sure that you know how find images also by using a transparency and dynamic geometry (using the tools provided in the applet).
