Transformations Spiders

Three spiders on transformations (both describing and drawing) that getting increasingly challenging from spider 1 to spider 3. Spider 1 contains reflections in the x and y axes, translations and rotations about the origin. Spider 2 contains reflections in horizontal and vertical lines (x=n or y=n), rotations around points away from the origin, and an enlargement. Spider 3 contains reflections in diagonal lines (y=-x), roattions away from the origin and fractional and negative enlargements where the centre is not the origin. They should encourage discussion and I hope the diagrams are large enough (they are as large as I can make them).
