Problem
A rotation taken clockwise from the positive x-axis is classified as a a) reflex angle b) negative angle c) positive angle d) zero angleIntuitive explanation
A rotation's classification depends on the sign convention we use. In standard mathematics, rotations measured counterclockwise from the positive x-axis are considered positive, while clockwise rotations are negative. So you're identifying which direction corresponds to which sign—the key insight is that "clockwise" always means we're going opposite to the standard positive direction, making it a negative angle.
