Rotations on a Coordinate Plane Practice

Front

What is the result of rotating a point (x, y) 180° about the origin?

Back

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

Front

How do you rotate a point 90° counterclockwise about the origin?

Back

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

Front

What are the coordinates of a point after a 270° clockwise rotation about the origin?

Back

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

Front

If a point is at (a, b), what are the coordinates after a 180° rotation about the origin?

Back

The coordinates will be (-a, -b).

Front

What is the effect of rotating a point 360° about the origin?

Back

The coordinates remain the same; the point does not move.

Front

What is the formula for rotating a point (x, y) 90° clockwise about the origin?

Back

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

Front

How do you determine the new coordinates of a point after a rotation?

Back

Use the appropriate rotation formula based on the angle and direction of rotation.

Front

What happens to the coordinates of a point when it is rotated 180° about the origin?

Back

The x and y coordinates are both negated.

Front

If point A is at (2, 3), what are the coordinates of A' after a 90° counterclockwise rotation?

Back

The coordinates will be (-3, 2).

Front

What is the result of rotating the point (-1, 2) 270° clockwise about the origin?

Back

The new coordinates will be (2, 1).
