How many vertices does a circle have?

Understand the Problem

The question is asking about the number of vertices in a geometric shape, specifically a circle. In geometry, a vertex is defined as a point where two or more curves meet; a circle is a smooth curve with no corners or intersections, hence it has no vertices.

More Information

A vertex is a point where two or more curves, lines, or edges meet. Since a circle is a smooth curve with no edges or corners, it does not have any vertices.

Tips

A common mistake is to confuse a circle with polygons. Circles are not polygons and thus do not have vertices or sides.
