How many angles or corners are there in a circle?

Explanation

Geometry is the part of mathematics that deals with shapes, sizes and figures. A triangle has three angles (corners) and three sides. A square has four angles and four sides. A square, a trapezoid and a rectangle are all kinds of squares, but differs in lengths of the sides or angles of the corners. A circle is different. It has no angles or sides, but consists of infinitely many points.
