Rotations Asynchronous Lesson 8/27/2021

How many quadrants are there on a coordinate plane?

How many degrees is a quadrant worth?

The clock is going in the __________ direction.

The clock is going in the __________ direction.

Rotate the point (5,5) around the origin 180 degrees counterclockwise. State the image of the point.

Rule: (x, y) ---- ( -x, -y)

Rotate the point (-3,-4) around the origin 180 degrees. State the image of the point.

Rule: (x, y) --- ( -x, -y)

Rotate the point (-5,8) around the origin 90 degrees clockwise. State the image of the point.

Rule: (x, y) ----- (y, -x)

Rotate the point (7,8) around the origin 90 degrees counter clockwise. State the image of the point.

Rule: (x, y) ---- ( -y, x)

If you were to rotate ABCD 90°clockwise about the origin, what would the coordinate of A' be?

Rule: (x, y) ----- (y, -x)
