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.
The term  axiom may also be used to refer to a background assumption. Example of a postulate: Through any two points in a plane there is exactly one straight line. A theorem is a statement that can be proven to be true based upon postulates and previously proven theorems.
