Software Authors:  Wang, Dongming 
Description:  GEOTHER (GEOmetry THeorem provER), a module of Epsilon, is an environment implemented by Dongming Wang in Maple with drawing routines and interface written previously in C and now in Java for manipulating and proving geometric theorems. In GEOTHER a theorem is specified by means of predicates of the form Theorem(H,C,X) asserting that H implies C, where H and C are lists or sets of predicates that correspond to the geometric hypotheses and the conclusion of the theorem, and the optional X is a list of variables used for internal computation. The information contained in the specification may be all that is needed in order to manipulate and prove the theorem. From the specification, GEOTHER can automatically assign coordinates to each point in some optimal manner; translate the predicate representation of the theorem into an English or Chinese statement, into a firstorder logical formula, or into algebraic expressions; draw one or several diagrams for the theorem  the drawn diagrams may be animated and modified with a mouse click and dragging, and saved as PostScript files; prove the theorem using any of the five algebraic provers; translate the generated algebraic nondegeneracy conditions into geometric/predicate form; generate an HTML, LaTeX, and/or PostScript file documenting the theorem and its proof.
