Use the slider to rotate the rectangle counterclockwise.

Question 1

What are the coordinates of B' after rotating the rectangle 90 degrees counterclockwise?

Question 2

What are the coordinates of B' after rotating the rectangle 180 degrees counterclockwise?

Question 3

What are the coordinates of B' after rotating the rectangle 270 degrees counterclockwise?

Use the slider to rotate the rectangle clockwise.

Question 4

What are the coordinates of B' after rotating the rectangle 90 degrees clockwise (aka -90 degrees)?

Question 5

What are the coordinates of B' after rotating the rectangle 180 degrees clockwise (aka -180 degrees)?

Question 6

What are the coordinates of B' after rotating the rectangle 270 degrees clockwise (aka -270 degrees)?

Question 7

Compare your answers from Questions 1 and 6. What do you notice about the coordinates?
