Summary

Geometry becomes painless - and even fun - once middle school and senior highchool students learn the subject's basic components and see how solving anyeometric problem is fitting parts together to solve an intriguing puzzle.hey learn the meaning of postulates and theorems, discover angles of allinds, find the relationships that exist between parallel and perpendicularines, and discover the characteristics of shapes such as triangles,uadrilaterals, and circles. The author introduces real-world geometryxperiments to make concepts less abstract, offers study strategies, andemonstrates how mini-proofs are the first step toward understanding formaleometry proofs.
