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). Suppose Susan rotates the same object around (1,2). 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.
