N1  - Includes bibliographical references; Chapter 1. Basic trigonometry functions of acute angles -- Chapter 2. Lines, planes and angles -- Chapter 3. Triangles -- Chapter 4. Quadrilaterals -- Chapter 5. Polygons -- Chapter 6. Circles
N2  - The millions of problems and theorems of plane geometry are considered huge to handle in full even nowadays. The stream of new problems is still wide and any attempt to tackle all the problems will seem to fail, for many reasons
