About The Book: This book on geometry reminds us that come what may Mathematics cannot be forgotten. Of course Euclid with his book 'The Elements' is the pioneer of Geometry. No less important are contributions due to Pythagoras and Ptolemy. This book contains several examples both difficult and somewhat easy and their solutions. Theorem no. 76, and solution of isosceles triangles with vertical angles 36 degree may strike excitement in you. CONTENTS: # Preface 9, Introduction 13, 1.
