Geometry Session 2: Triangles and Quadrilaterals
 

In this session, you will build triangles and quadrilaterals to explore their properties. Classification is an important part of geometry and other areas of mathematics. By creating and manipulating triangles and quadrilaterals, you will develop a sense of logical classifications and how different figures are related.

In This Session:

Part A:

Different Triangles

Part B:

Linkage-Strip Constructions

Part C:

Building Towers

Homework

 


For information on required and/or optional materials for this session see Note 1.
