Question

For the point 4(-3,7) marked on the diagram; find its image after each of the following: (@) A rotation of 90 degrees counterclockwise about the origin: A(-3,7), (b) A rotation of 90 degrees clockwise about the origin: A(-3,7), (c) A rotation of 180 degrees counterclockwise about the origin: A(-3,7)

Answer 1

point(3,7)

90 degree CCW rotation about the origin = (-7,3)

90 degree CW rotation about the origin = (7,-3)

180 degree CW rotation about the origin = (-3,-7)
