... Contrapositive - In a plane, if two lines are not parallel and intersect another line, then they are not perpendicular to the intersected line. True Converse - If a quadrilateral is a rectangle then it is a square. False Inverse - If a quadrilateral is not a square then it is not a rectangle. False ...

... 7. Use the properties of logarithms to prove that the following three properties of distance are satisfied in the Poincaré model. (a) Dist(A, B) = Dist(B, A). (b) Dist(A, B) ≥ 0. (c) Dist(A, B) = 0 if and only if A = B. Note: The triangle inequality also holds, but you do not need to prove it. ...

Duality (projective geometry)

In geometry a striking feature of projective planes is the symmetry of the roles played by points and lines in the definitions and theorems, and (plane) duality is the formalization of this concept. There are two approaches to the subject of duality, one through language (§ Principle of Duality) and the other a more functional approach through special mappings. These are completely equivalent and either treatment has as its starting point the axiomatic version of the geometries under consideration. In the functional approach there is a map between related geometries that is called a duality. Such a map can be constructed in many ways. The concept of plane duality readily extends to space duality and beyond that to duality in any finite-dimensional projective geometry.
