square has four sides and four corners, while a circle has only one side and no corners. that the Reuleaux triangle has three sides and three corners. As an exercise, the reader can compute the
Does a circle have no corners or infinite?
A circle is made up of all the points a particular radius from the center - no lines nor line segments at all - and therefore has no corners. The individual points are not corners nor is there any space leftover between them.
Do circles have sides and corners?
It might be more defensible to say that a circle has infinitely many corners than infinitely many sides (although this is not a question that seems to get asked very often). To start with, if a corner of a square is a point at which its boundary line is not straight, then every point on the circle satisfies that.
