Constructing Quadrilaterals

Activity Overview

In this activity, students will construct different types of quadrilaterals from the quadrilateral hierarchy. This activity asks for constructions based on a minimal definition of the quadrilateral. The activity will reinforce the difference between a construction and a drawing.

Before the Activity

  • Install the Cabri Jr. App on the students' graphing calculators using TI-Connect™, a TI Connectivity Cable and the Unit-to-Unit Link Cable
  • See the attached PDF file for detailed instructions for this activity
  • Print pages 135 - 136 from the attached PDF file for your class
  • During the Activity

    Distribute the pages to your class.

    Follow the Activity procedures:

  • Construct a quadrilateral, a kilte, a trapezoid, an isosceles trapezoid, a parallelogram, a rhombus, a rectangle, and a square
  • Drag the vertices and sides of the quadrilaterals constructed to ensure the minimal definitions are retained
  • After the Activity

    Review student results:

  • As a class, discuss questions that appeared to be more challenging
  • Re-teach concepts as necessary
