Rotational and Reflectional Symmetry of 17 images 
For each image (k=0 to k=16) find out how many rotational and reflectional symmetries it has. Also, check to see how many degrees you need to rotate an image before it overlaps with the original. 

Geogebra  Multiple Transformations of Original Shape 
Experiment with this page. Use the arrow tool and drag points to see what happens. Try to make your own page from scratch to make a design that includes rotations, reflections, and vector translations.
