1. That which is considered and established as a principle;
hence, sometimes, a rule.
[1913 Webster]
Not theories, but theorems (?), the intelligible products of contemplation, intellectual objects in the mind, and of and for the mind exclusively. --Coleridge. [1913 Webster]
By the theorems, Which your polite and terser gallants practice, I re-refine the court, and civilize Their barbarous natures. --Massinger. [1913 Webster]
2. (Math.) A statement of a principle to be demonstrated. [1913 Webster]
Note: A theorem is something to be proved, and is thus distinguished from a problem, which is something to be solved. In analysis, the term is sometimes applied to a rule, especially a rule or statement of relations expressed in a formula or by symbols; as, the binomial theorem; Taylor's theorem. See the Note under {Proposition}, n., 5. [1913 Webster]
{Binomial theorem}. (Math.) See under {Binomial}.
{Negative theorem}, a theorem which expresses the impossibility of any assertion.
{Particular theorem} (Math.), a theorem which extends only to a particular quantity.
{Theorem of Pappus}. (Math.) See {Centrobaric method}, under {Centrobaric}.
