===Objective===
#Using Geogebra to accurately construct and label geometric figures
#Visualizing how triangles are formed
#Understanding properties of triangles
===What prior skills are assumed===
#Basic familiarity with the Geogebra tool bar and the different features
#Working with text document and adding pictures
===What resources do you need===
#Computer lab with projection
#[[Learn Firefox|Access to internet]]
#Handout for [[Learn Ubuntu|Ubuntu]]
#Handout for [[Learn Geogebra|Geogebra]]
#Geogebra files for demonstration
===What digital skills will you learn===
#Learning to work with interactive applications, with given input
#Creating, saving files with Geogebra
#Accurately drawing and measuring geometry figures
#Inserting pictures and completing the worksheet
===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 triangle can be constructed.
You will use the following Geogebra files which 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)

<br> Your teacher will demonstrate the following to you:
#Drawing lines
#Plotting intersection points
#Identifying and measuring angles
#Marking a triangle
#Identifying vertically opposite angles
#Identifying exterior angles
#Verifying angle sum property
#Marking segments and measuring length
====Student activities====

After the demonstration lesson, you will learn to construct the following:
#Three intersecting lines with the formation of a triangle
#Exploring the properties of a triangle and completing a worksheet
===Portfolio===
#Your completed Geogebra files will be the addition to your digital portfolio.
#Completed worksheet
