Unit 5: Seeing Structure and Generalizing (MP7 and MP8)

5.3 Geometry Examples of Structure and Generalization

Structure in geometry involves understanding basic properties of geometric figures and how they relate to each other. It also entails understanding geometric relationships such as perpendicularity and parallelism, and the connection between angle relationships.

Generalization in geometry is exemplified in a well-known middle school activity where students tear off the three corners of a triangle and arrange them to form a straight line. This is just one example of two mathematical practices at work in the geometric context.
