Rotation on Coordinate Plane

Front

What is the rule for a 180 degrees rotation around the origin?

Back

The coordinates of each point (x, y) become (-x, -y).

Front

What is the original figure prior to a transformation called?

Back

Pre-image.

Front

What is the result of a 90 degrees clockwise rotation around the origin for the point (x, y)?

Back

The new coordinates will be (y, -x).

Front

What is the result of a 90 degrees counterclockwise rotation around the origin for the point (x, y)?

Back

The new coordinates will be (-y, x).

Front

What happens to the coordinates of a point when it is rotated 180 degrees around the origin?

Back

The coordinates (x, y) become (-x, -y).

Front

If point A(2, 3) is rotated 90 degrees clockwise, what are the new coordinates?

Back

(3, -2).

Front

If point B(-1, 4) is rotated 90 degrees counterclockwise, what are the new coordinates?

Back

(-4, -1).

Front

What is the transformation called when a figure is turned around a fixed point?

Back

Rotation.

Front

What is the angle of rotation for a full rotation?

Back

360 degrees.

Front

If a figure is rotated 270 degrees clockwise, what is the equivalent counterclockwise rotation?

Back

90 degrees counterclockwise.
