In HS geometry, our teacher started showing us basic constructions with compass and ruler: bisecting a line segment, drawing a line perpendicular to another line, and bisecting an angle. Then, at the end of class, he mentioned that no one had ever succeeded in figuring out a method to trisect angles. He did not mention that it had been proven that you couldn't (in the general case).
I spent the entire evening trying to trisect the angle.
- pavel_lishin 13y agoIt seems like a useful way to spend an evening for someone learning geometry.
- chinpokomon 13y agoI think it was explained that way to me too. I also spent a lot of time trying different ways. In hind sight, that was probably one of the best ways I could have been taught. I was challenged to try and do something that others had not.
