What is the main feature of a circle?
Answer and explanation
Correct answer: It has no corner
A circle is a closed plane shape whose boundary is a continuous curved line. Every point on that boundary is at the same distance from the centre. Because the boundary has no meeting points between straight sides, the shape has no vertex, angle, or corner. This curved, round outline is the main visual feature that distinguishes a circle from polygons such as squares and triangles.
Option A says that a circle has no corner, which is correct. A shape with four equal sides is a square or another quadrilateral, not a circle. A circle is not defined by being slanting, and it does not consist of straight lines. Its boundary is curved throughout. Therefore the identifying feature is the absence of corners, and option A is the correct choice.
