1. Rotate ABCD 90 degrees clockwise around Q.[br][br]2. Rotate ABCD 180 degrees around R.[br][br][br](If you click the third button from the right (that looks like a percentage sign), you will see a bar pop up with all the tools for transformations.)
What information do you need to do a rotation?
Why don't you need to know the direction of rotation when the angle of rotation is 180 degrees?
