C2 Angle Rules?

I've forgotten all the angle rules! Apart from the basic one such as angles around a point equal 360, could someone link me with all the basic angle rules that I will have to know for C2?


Thanks

What do you mean? Like this kinda stuff?

sinθ=k    θ=arcsink\sin\theta = k \implies \theta =\arcsin k

and

180arcsink,360+arcsink,180-\arcsin k, 360+\arcsin k,

etc.

No I meant as in Z-angles, C-angles, and all other rules.

As far as I know, you don't need them for C2 (Edexcel, not sure about other exam boards)
