Rotation Using the Rules

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

• (-7,-8)

• (8,-7)

• (-8,7)

• (8,7)

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

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

• (8,-5)

• (8,5)

• (5,-8)

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

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

• (-7,-8)

• (8,-7)

• (-8,7)

• (8,7)

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

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