**Morley Tirangle**

This is proof due to D.J.Newman I found in the web.

The idea to start with a equilateral triangle and arbitrary
angles α+β+γ=60.
Then construct A, B and C. We have to show φ=α
finally. To do this, use the sine theorem.

### Technical Information

There is not much space for the angles here. So we use
invisible angles. The labels are shown nevertheless.
