Midsegments of Quadrilaterals

Activity Overview

In this activity, students will extend their understanding of midsegments by investigating the midsegments of a quadrilateral and the midsegment quadrilateral.

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

Use the TI-Navigator™ to transfer the attached Cabri Jr. AppVar files to each calculator

See the attached PDF file for detailed instructions for this activity

Print pages 149 - 150 from the attached PDF file for your class

During the Activity

Distribute the pages to your class.

Follow the Activity procedures:

Use the AppVar to go directly to the exploration section

Construct the midsegment quadrilateral of a general quadrilateral

Investigate the properties of a quadrilateral

Drag the vertices and /or sides of a quardrilateral and observe whether these properties are true for a quadrilateral

Use various measurement tools to investigate the relationship between a quardrilateral and its midsegment quardrilateral

After the Activity

Review student results:

As a class, discuss questions that appeared to be more challenging

Re-teach concepts as necessary
