Syn. 3. ring, halo, corona. 11. CIRCLE, CLUB, COTERIE, SET, SOCIETY are terms applied to restricted social groups. A CIRCLE may be a little group; in the plural it often suggests a whole section of society interested in one mode of life, occupation, etc.: a sewing circle; a language circle; in theatrical circles. CLUB implies an association with definite requirements for membership and fixed dues: an athletic club. COTERIE suggests a little group closely and intimately associated because of congeniality: a literary coterie.
SET refers to a number of persons of similar background, interests, etc., somewhat like a CLIQUE (See ring1) but without disapproving connotations; however, it often implies wealth or interest in social activities: the country club set. A SOCIETY is a group associated to further common interests of a cultural or practical kind: a Humane Society.

I
Geometrical curve, one of the conic sections, consisting of the set of all points the same distance (the radius) from a given point (the centre).

A line connecting any two points on a circle is called a chord, and a chord passing through the centre is called a diameter. The distance around a circle (the circumference) equals the length of a diameter multiplied by π (see pi). The area of a circle is the square of the radius multiplied by π. An arc consists of any part of a circle encompassed by an angle with its vertex at the centre (central angle). Its length is in the same proportion to the circumference as the central angle is to a full revolution.
