How to divide a 90 degree angle into 3 equal parts.

This will only work for trisecting a 90-degree angle, but the current title of the video implies that it's a general-case solution for any angle.

"An angle" is not any angle, but a specific angle. The header is a bit miseading, because the general problem ist still unsolved.

@@Wimmas No offence taken, but I was rather disappointed, because at first glance I thought, the miracle had happened 🙂
