Features: It is not easy to systematically master the method of adding auxiliary lines. This book attempts to explore the basic principles of adding auxiliary lines to help junior high school students grasp the fundamental methods of solving plane geometry problems. Most of the examples and exercises in this book are selected from recent junior high school examination questions from various regions. We hope that students will fall in love with this book, gain benefits from it, and master the basic knowledge of plane geometry, the fundamental thinking process for solving plane geometry problems, and gradually become masters of the mathematical garden.
