Classifying Triangles by Line and Angle Properties
Triangles abound in this module! In this series of investigations, students will construct and use a plethora of Zometool triangle models to develop a system of classifying triangles by:
(a) examining the relationships between the side lengths of triangles, or line properties;
(b) examining the relationships between the angle measurements of triangles, or angle properties; and
(c) examining the relationships between the line and angle properties of triangles.
Throughout this module, students will learn to reason with geometric properties in an effort to better identify and understand the major types of triangles that exist in structures around us.
