Basic Geometry: Plane Geometry

Preface Basic Geometry
This book is intended to serve as a reference for the contents of Basic Geometry Disciplines taught in Elementary and Middle School.The content starts with the most basic definitions of point, line, and plane. Following it is presented the relationships between these elements showing all postulates.
The third chapter introduces the triangles, all of its properties, postulates and theorems.
The next chapter presents the Quadrilaterals, all its properties, postulates and theorems.
The fifth chapter discusses the circumference and the circle, with all their properties, relationships and theorems.
The sixth chapter is dedicated to polygons, its properties and construction.
The seventh and final chapter shows ellipse, parabola and hyperbole curves, their construction and properties.
The content contained in this book is basic to the next book on spatial geometry, which is the object of study in various disciplines at High School.
