A General Certificate of Secondary Education math review has class members make basic constructions. Using a protractor and a ruler along with a compass, pupils develop drawings of triangles with given measurements. Scholars use their construction knowledge to draw accurate versions of quadrilaterals, too.

Instructional Ideas

• Lead a discussion on the geometry behind the constructions
• Have the class identify the congruence postulates the triangle drawings verify

Classroom Considerations

Pros

• The worksheet includes space for all the constructions
• Includes an answer key that shows the individual constructions

Cons

• The video goes beyond the types of constructions needed for the worksheet
