... Conversely, if one side of an inscribed triangle is a diameter of the circle, Then the triangle is a right triangle and the angle opposite the diameter is the right angle. A quadrilateral can be inscribed in a circle if and only if its opposite angles are supplementary. If a tangent and a chord inte ...

... prove something will allow you to do well. The need for knowing how to write procedures, and express ideas, in proper mathematics makes this first chapter a very important one. In it you will be introduced to proofs, which is the formal name of what colloquially one could call ‘a thorough and comple ...

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.
