How to use: Define a shape by clicking points on the grid (or use the sample shape). Then choose a transformation. The original (blue) and the image (orange) appear together, and the coordinate rule shows what each transformation does to every (x, y).

Tip: Use a non-symmetric shape (a scalene triangle, an L-shape, or an asymmetric quadrilateral) so the transformation is easy to see. The image (orange) is what you get when you apply the rule to every point of the original (blue).
