Attributes of Polygons
The attributes of polygons relate to the concept of geometric figures and their properties. Geometry consists of
the study of geometric figures of zero, one, two, and three dimensions and the relationships among them.
Students study properties and relationships having to do with size, shape, location, direction, and orientation
of these figures. There are critical attributes that are used to classify polygons.

Mini-me activity.
Explain/ Share, Discuss and Analyze
Have students display their posters and describe how they
created their Mini-me.
This is the culminating activity for 7-2 Similar Polygons.
Students use what they have learned about proportional
relationships in a creative way.
Have students to design and calculate a smaller version of
themselves (a reduction). Students take real-world
measurements and use a table provided calculate the
proportionate relationship.
