Description of activity with detailed steps

Teacher led activity

We will continue the work you did with Geogebra last year to learn more mathematics. Your teacher will display the file below and ask you to explore how quarilaterals can be constructed.

You will use the following Geogebra file for this lesson. (You can click on the image to download the Geogebra file, you can do this for any Geogebra file in the text book)


Your teacher will demonstrate the following to you:

  1. Drawing segments after plotting points
  2. Measuring and labeling segments
  3. Identifying and measuring angles
  4. Using the rounding off option
  5. Marking a quadrilateral
  6. Verifying angle sum property
  7. Making a textbox with a conclusion
  8. Demonstrating the use of an input box like a check box

Student activities

  1. Four intersecting lines with the formation of a quadrilateral - try it with all equal sides, two sides equal, etc. Did you notice any difficulty in construction?
  2. Exploring the properties of a quadrilateral and completing a worksheet


  1. Your completed Geogebra files will be the addition to your digital portfolio.
  2. Completed worksheet
