2. CIRCLE
 A circle is a simple shape of Euclidean geometry that
is the set of all points in a plane that are a given
distance from a given point, the centre. The distance
between any of the points and the centre is called
the radius. It can also be defined as the locus of a
point equidistant from a fixed point.
