Triangle rst is rotated 90° in a clockwise direction. what is the name of the image after the rotation?

Umm... there is no picture for it. But to partially answer your question, I'll give you a little tip. From the problem, it is a 90 degrees clockwise direction. So the coordinates of the preimage to the image would be (x,y) to (y,-x). Hope this helps. If you have any questions, just ask me. ;)
