In this tutorial, we use the Parallel Line tool of GeoGebra to construct a parallelogram. To construct the parallelogram, we first construct points A, B and C. Then, we use the Parallel Line tool to construct a line parallel to AB and passing through point C, then construct another line parallel to BC and passing through point A. We use the intersection of the two lines to determine the fourth vertex of our parallelogram.
In this tutorial, we use GeoGebra in constructing a rolling circle. This way, we would be able to relate the diameter of the circle to its circumference. Moreover, this activity will reinforce the relationship between the angle and radian measure.

Note: Although this is the 23rd of the GeoGebra Tutorial Series, just like other GeoGebra tutorials, it is independent from others. This means that you can follow this tutorial step-by-step, without needing to learn the previous twenty two tutorials.
In this tutorial, we are going to use the spreadsheet to perform basic data representation. We will plot a frequency table of grouped data and perform basic computations using the spreadsheet window. After the data is completed, we will construct a histogram. » Read more
