Another part is dedicated to the use of complex numbers and barycentric coordinates, granting the reader both a traditional and computational viewpoint of the material. WebbLemma. (Duality Angle Chasing) Denote with apostrophe the duals of points and lines in some duality with center O.Then (i) O\AB= O\A 0B, (ii) O\pq = O\p 0q, (iii) O\Ap = \A0p0. Proof. The proof is straighforward, using only the fact that OAis perpendicular to A0. •(i),(ii) Denote pthe polar of Aand qthe polar of B.Then there exists a rotation with angle AOB … Webbspecific form of the three points of intersection lines on the sides of the triangle.
