GeoGebra Basic Construction 6 – Constructing a Parallelogram

In this tutorial, we  use the Parallel Line tool of GeoGebra to construct a parallelogram.  To construct the parallelogram, we first construct points AB 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.
