Geometric Brain TeasersI have a series of questions that I have been trying to solve and I need help with the solutions, they are driving me crazy! Each question needs to be proven also, not just constructed. Here they are: #2 20101118 00:07:47

Re: Geometric Brain TeasersOK got it. But it's a bit of a chase of angles around the diagram so rather than add it to the above post, I thought it would be easier to show as a separate post. My geometry software insists on showing A, B N and M on the same circle (because they are!) but that makes it hard to avoid making assumptions that haven't been justified. So I started with a new diagram with A, B and M as before but with N deliberately shown not on the circle. My aim is to show it is.
