Coordinate Geometry - Department of Mathematics

ondly, in each kind of geometry there are normal form theorems which can be used to simplify coordinate proofs. For example, in a ne geometry every tri-angle is equivalent to the triangle whose vertices are A0 = (0;0), B0 = (1;0), C0 = (0;1) (see Theorem 3.13) and in Euclidean geometry every triangle is
