    This geometry puzzle is really tough. Without using trigonometry and trigonometrical properties of triangles, it cannot possibly be solved.

    I presume he means without using trig functions. Of course you wil have to use properties if triangles to solve .... wont you?!??!

    This is a "mystic hexagon" and is part of Pascal's Theorem. I was reading about this today. "Men of Mathematics" E. Bell

    I've read it like 10 times
