Back

(-3, -4).

Front

If point A is at (5, -2), what are the coordinates of A' after a 90° counterclockwise rotation about the origin?

Front

What is the definition of rotation in geometry?

Back

Rotation is a transformation that turns a figure around a fixed point, called the center of rotation.

Front

What is the center of rotation when rotating around the origin?

Back

The center of rotation is the point (0, 0) in the coordinate plane.

Front

How do you determine the new coordinates after a rotation?

Back

Apply the rotation rules based on the angle of rotation and the original coordinates.

Front

What happens to the coordinates of a point when it is rotated 90° clockwise about the origin?

Back

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