A coefficient in literal form in an algebraic term is called a literal coefficient. In mathematics, a coefficient is basically a multiplicative factor in a term but in algebra, a literal coefficient is a multiplying factor which contains one or product of more literal numbers in an algebraic term. Examples $(1) \,\,\,\,\,$ $7a$
These properties apply to all regular polygons, whether convex or star. A regular n-sided polygon has rotational symmetry of order n. All vertices of a regular polygon lie on a common circle (the circumscribed circle), i.e., they are concyclic points. That is, a regular polygon is a cyclic polygon.
1 Postulates: statements that are assumed to be true without proof (for example, an angle has only one bisector)  Axioms: self-evident truths or the basic facts that are accepted without any proof (for example, a straight line can be drawn between any two points)
