Extending Beyond (Part 7)

Let's go back and focus on one point: (7,1). Fill in this column quickly again. Here, rotation center = (0,0). You can use the app below if you need to.

Now, move O in the app above anywhere you'd like! Here, we're changing the center of rotation. Let's explore what happens when we spin (7,1) around O = (1,2) instead. Move O to (1,2) and fill in the info below.

Suppose Jane rotates an object around (0,0). [br]Suppose Susan rotates the same object around (1,2). [br][br]How can Susan easily determine coordinates of images in her transformation (rotating about (1,2)) if she knows the effects of Jane's transformation (rotating about (0,0))? Describe.
