Yes, I knew about that one. 😊🥰It is about the midpoint angle is the double size of the other one. But it is upside down from what I have learnt. Idiot…
I did not know that the sum of opposite angles are 180° for quite small quadrilaterals, but of course it must be. Otherwise it is not a rule. Then we have that new theorem that is the great opener for the solution. Do you have a name for it? I have never seen it.

Haha it's okay! Most people have forgotten this :)
