This is an interactive course on [b][color=#1551b5]geometric constructions[/color][/b], a fascinating topic that has been ignored by the mainstream mathematics education. It is all about drawing geometric figures using specific drawing tools like straightedge, compass and so on. This classical topic in geometry is important because
[list]
[*]the foundation of geometry is mostly inspired by what we can do with all these drawing tools, and
[*]it involves a lot of beautiful mathematics that shows the interplay between geometry and algebra.
[/list]
There are numerous construction exercises in this course. [color=#c51414]When you successfully construct the required geometric figure(s) in each exercise, the "[b]Well done![/b]" message will appear.[/color]
[b][color=#c51414]Prerequisite for this course[/color][/b]:
[list]
[*]A little bit set theory
[*]High school geometry and algebra
