A vertical line rotates 45 degrees clockwise each step. If it starts vertical, what is its orientation in step 3?
💡 Explanation
Step 1: Vertical (0°). Step 2: 45° CW (diagonal top-right to bottom-left). Step 3: 90° CW (horizontal). Wait: vertical -> 45 -> 90. If it rotates 45 degrees each step: step 1 (0°), step 2 (45°), step 3 (90° = horizontal). Let's verify the options: a) Horizontal, b) Diagonal, c) Diagonal, d) Vertical. The 3rd step is indeed horizontal. Let's check the rotation: step 1 (0), step 2 (45), step 3 (90). So the answer is a (Horizontal).
