I'm currently doing some maths work from home, and realise that I tend to struggle when it comes to using the cosine, sine, sohcahtoa, and pythagoras rules.
Not so much using them, I can use them easily, but remembering when to use each one.

Does anyone have an easy way to remember when to use each of these rules on a triangle?

Edit: I do know how to use these rules. I'm more like asking how to remember when
