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.

7.5 Alternate Opener (Holt online)
Engage/Set-up/Launch
Students work in teams to measure all dimensions of the
classroom (length, width, height) using tape measures or
meter sticks. See Using Proportional Relationships Handout
7.5 Texas Practice B (Holt online). Students work with
partners or in small groups. Teacher checks in with each
group.
Each group explains to the class (in 2-3 minutes) one of the
questions, from 1-6 on Texas Practice B. May use document
camera or make small posters.
As a class, discuss the final answer for questions 7-9 on
Texas Practice B.
