Summary: This paper describes the mechanization of the proofs of the first eight chapters of W. Schwabhäuser, W. Szmielew and A. Tarski’s book [Metamathematische Methoden in der Geometrie. Berlin: Springer (1983; Zbl 0564.51001)]. The proofs are checked formally using the Coq proof assistant. The goal of this development is to provide foundations for other formalizations of geometry and implementations of decision procedures. We compare the mechanized proofs with the informal proofs. We also compare this piece of formalization with the previous work done about Hilbert’s Grundlagen der Geometrie. We analyze the differences between the two axiom systems from the formalization point of view.
