3-1 Practice

There is a square, ABCS, inscribed in a circle with center D. What is the smallest angle we can rotate around D so that the image of A is B?

Points A, B, C, and D are vertices of a square. Point E is inside the square. Explain how to tell whether point E is closer to A, B, C, or D. Which of the following constructions or transformations could be used to answer this question?

Sometimes reflecting a point over m has the same effect as rotating the point 180 degrees using center P. Select all labeled points which have the same image for both transformations.
