A square with a center dot is rotated. Where does the dot appear after rotation?

• A. Top-left
• B. Center
• C. Top-right
• D. Bottom-left

Answer: (B)

When a shape is rotated around its center, every point moves along a circle centered at that point. The center point itself has zero distance from the center, so it doesn’t move at all. Since the dot sits right at the square’s center, it stays exactly in the middle as the square rotates.
