An analytic proof in elementary geometry is a proof that represents geometric objects in a coordinate
system and establishes the desired result by algebraic reasoning. It is also
called a coordinate proof. This method belongs to analytic
geometry and contrasts with a synthetic proof
(Baldwin and Mueller 2024, p. 4).
In proof theory, the term analytic proof has a different meaning referring to restrictions on the formulas occurring
in a proof, rather than to the use of geometric coordinates
(Baaz et al. 2008, p. 160).
