This is an interactive course on geometric constructions, 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.
Use the coordinate plane below to draw a a 2D design for a new building. It needs to have four right angles and a corner at point (4,3). Hints: Click and then ; Click one spot and then another spot to create a line *Extras: Try drawing different shapes with similar properties.
