Outline
Circles: Angle, Chord, Secant, Tangent Properties & Theorems
In this GeoGebra book you will find several attached worksheets.
Please refer to each worksheet for a description of the illustrated circle properties and theorems.
This book is a positive example of how students can learn properties and theorems related to circles while using a user friendly graphing program called GeoGebra.
I would recommend that educators consider creating assignments for students to create such books that illustrate interactive geometry postulates, theorems, and corolarrys.
Additional written descriptions and explanations are included on each of the five included worksheets.
