## GeoGebra Tutorial Video 2 – Constructing a Square

This is the second video tutorial on using GeoGebra. This is the video of the article GeoGebra Tutorial 3 – Constructing a Square. Sorry for some grammar lapses (I am not very good in impromptu), and  I am really having a hard time imitating American accent to make most of the viewers understand this video. Sometimes my tongue gets twisted — so twisted that it automatically adds “s” to singular nouns (chuckles) like squares instead of square.

Anyway, this is a math blog, so I suppose it is appropriate for us to leave the grammar stuff to language teachers, although you are very much welcome to comment on errors, grammar may it be.

My next video is on Graphs and Sliders, so keep posted.

## GeoGebra Tutorial 3 – Constructing a Square

This is the third tutorial of the GeoGebra Intermediate Tutorial Series and the fourth part of the GeoGebra Basic Construction Series. If this is your first time to use GeoGebra, I strongly suggest that you read the GeoGebra Essentials Series.  This tutorial, answers the following problem using GeoGebra.

Problem: How will you draw an equilateral triangle without using the Regular polygon tool?

In this tutorial, we mimic compass and straightedge construction using the Circle tool, the Parallel Line tool, the Perpendicular Line tool of GeoGebra to construct a square instead of using the Regular Polygon tool.  We will also reinforce the use of the Angle tool, this time, learn how to use it to measure angle using three points. » Read more
