A geometry proof — like any mathematical proof — is an argument that begins with known facts, proceeds from there through a series of logical deductions, and ends with the thing you’re trying to prove. Geometry proofs follow a series of intermediate conclusions that lead to a final conclusion: Beginning with some given facts, say A and B ...Proof: In order to minimize algebraic complexity, it is very helpful to coordinate the plane in such a way as to make the algebraic arithmetic as easy as possible being careful, of course, to be completely general in the assignment. A common simplification is with one side of a figure being studied along the x -axis and an important point (0, 0 ...
