Features: This book is an invaluable "sharp weapon" for both exam preparation, competitions, and further studies. It primarily introduces new approaches to solving plane geometry problems, refinement, generalization, thinking from the opposite angle, the Jing Tian problem and the section formula, achieving multiple goals with one arrow, proving the Pappus theorem and the Gauss line theorem using the point elimination method, and angle-sharing triangles and the angle-sharing theorem, among others. Many middle school students find plane geometry problems difficult, and the difficulty lies in the endless variations of plane geometry problems, making it hard to discern general patterns. Academician Zhang Jingzhong teaches middle school students a new method for solving plane geometry problems, making it as systematic as solving algebraic equations. The book also presents a fresh perspective on using area formulas to cleverly solve trigonometric exercises.
