Students learn how to construct triangles when given SAS.

As learning progresses they construct more complex shapes using the same techniques.

**Differentiated Learning Objectives**

- All students should be able to construct a triangle using a pair of compasses, protractor and ruler.
- Most students should be able to construct a quadrilateral using a pair of compasses, protractor and ruler.
- Some students should be able to construct a polygon using a pair of compasses, protractor and ruler.
