A shape with four sides has more vertices because there are more points where edges (straight lines) meet than a 3-sided shape.
Most shapes will have more than two sides. If the sides are straight lines, the shapes MUST have more than two sides.

A shape with more than 10 sides may be called a polygon - but only if all the sides are straight lines - and there is nothing in the question to suggest that they are.
