Do not get confused, this is not GPS but GSP. Again, GSP. A short introduction on GSP is that it is a popular commercial interactive geometry software program for exploring Euclidean geometry, algebra, calculus and other areas of mathematics. It was created by Nicholas Jackiw. GSP includes the traditional Euclidean tools of classical Geometric constructions; that is, if a a figure can be constructed with a compass and straight-edge, it can also be constructed using this program.

So, this is what Puan Azyan taught us in class. I do not want to animate it because I want you people to have a go with it and see the results. Have a try okay! :)
p/s: The instructions for building a parabola is already typed and highlighted on the print screen below.
