Shapes And Designs: Two-Dimensional Geometry (Connected Mathematics 2)

The goal of Shapes and Designs is to have students discover and analyze many of the key properties of polygonal shapes that make them useful and attractive.
This unit focuses on polygons and develops these two themes:
• How do the measures of angles in a polygon determine its shapes and uses?
• How do the lengths of edges in a polygon determine its shapes and uses?
Each investigation focuses on some key properties of figures and the importance of those properties in applications. Students are periodically asked to identify differences among particular classifications of polygons. Students are also asked to find and describe places where they see different polygons and to think about why those shapes are used.
