A graphical user interface for formal proofs in geometry
We present in this paper the design of a graphical user interface to deal with proofs in geometry. The software developed combines three tools: a dynamic geometry software to explore, measure, and invent conjectures; an automatic theorem prover to check facts; and an interactive proof system (Coq) to mechanically check proofs built interactively by the user.
