"Trisecting an angle"

 Hi, i think my friend has found out how to trisect an angle. This is one of the "impossible"geometry problems. What should i do?

 Seems like this is a great feat for your friend to achive. You should submit your friend's idea/solution to your math teachers/professors and to various websit's such as this one for verification of data and correctness. Since I know no squat about trisecting an angle, don't ask me. But just get it out to many people and get their feedbacks. Even though I doubt that your friend has done the impossible, there may be a chance that something big might happen. But just get this to credible websites and people you know, most importantly to mathematical profession people, like your math teacher. I would like to hear from you about this later! See YA!

The problem is only "impossible" in general by compass and straightedge. With other implements it's quite possible. If your friend claims to have solved the Impossible One, do not bother. Recommend your friend a nice book by Underwood Dudley, The Trisectors.

 The only legal way to trisect an arbitrary angle is by using the revised version of Schnittker's Theorem. The original theorem worked for most angles but did not exclude cases that were not directly trisectable. The new theorem should be available soon.

 Trisecting an angle is no big deal. The catch is that it is to be done with nothing but a compass and a ruler (not allowed for measuring). If your friend did it this way, I suggest you go over it again because it has been proved that it cannot be done.
