Multiple Choice

Rotation in the plane is best described as:

Rotation in the plane is turning a figure about a fixed point by a given angle. During a rotation, every point moves along a circle centered at that fixed point, keeping the same distance from the center, so the overall shape stays congruent to the original. The center stays in place, and the turn can go clockwise or counterclockwise. This is different from other transformations: a shear distorts lengths and angles, dragging without rotating translates the figure, and scaling changes the size relative to a point rather than just turning.
