Rotation Rules

Front

What is the rule for a 90° counterclockwise rotation about the origin?

Back

(-y, x)

Front

What happens to the size of a figure when it is rotated?

Back

The size remains the same.

Front

What is the rule for a 270° clockwise rotation about the origin?

Back

(-y, x)

Front

What is the rule for a 90° clockwise rotation about the origin?

Back

(y, -x)

Front

What happens to the shape of a figure when it is rotated?

Back

The shape remains the same.

Front

What is the general effect of rotation on the coordinates of a point?

Back

The coordinates change based on the angle of rotation.

Front

How does a 180° rotation about the origin affect the coordinates of a point (x, y)?

Back

The coordinates become (-x, -y).

Front

What is the difference between clockwise and counterclockwise rotation?

Back

Clockwise rotation moves in the direction of a clock's hands, while counterclockwise moves in the opposite direction.

Front

What is the rule for a 360° rotation about the origin?

Back

The coordinates remain the same (x, y).

Front

How can you determine the direction of rotation for a given angle?

Back

Angles measured positively indicate counterclockwise rotation, while negative angles indicate clockwise rotation.
