Geometry Revisited (New Mathematical Library)

Among the many beautiful and nontrivial theorems in geometry found in Geometry Revisited are the theorems of Ceva Menelaus Pappus Desargues Pascal and Brianchon. A nice proof is given of Morleys remarkable theorem on angle trisectors. The transformational point of view is emphasized: reflections rotations translations similarities inversions and affine and projective transformations. Many fascinating properties of circles triangles quadrilaterals and conics are developed.
