Identifying the Direction of Rotation
Triangle ABC has coordinates A(–4, 1), B(–3, 2), and C(–2, 1). The triangle is rotated about the origin and has image coordinates A’(1, 4), B’(2, 3), and C’(1, 2).

What is the angle and direction of rotation?
180° clockwise
180° counterclockwise
90° counterclockwise
90° clockwise

90° clockwise

Explanation: A 90° clockwise rotation about the origin sends (x,y) to (y,−x).
Check: A(−4,1) → (1,4), B(−3,2) → (2,3), C(−2,1) → (1,2), which matches the given image coordinates.
