Formulas for any transformation

As a geometry teacher, I find that I often want to give my students a transformation rule and see if they can identify the type of transformation. But making up transformation rules one-by-one got tiring. So I sat down and figured out the general form of each kind of transformation rule: the general form for any reflection, the general form for any rotation, and the general form for any dilation.

Here are the results. Enjoy!
