A circle has 0 sides.
Explanation:
- A side is typically defined as a straight edge of a polygon.
- A circle is a continuous curve with no straight edges or corners.
- Therefore, it does not have any sides like polygons do.
If you think about shapes like triangles, squares, or pentagons, they have 3, 4, and 5 sides respectively, all straight. But a circle is smooth and round, so it has none.
