Answer 1

Answer:

yes otherwise you will be quite unable to solve geometry

Answer 2

Answer:

Not Necessary but you have to understand the pythagoras theorem before starting trigonometry.

I have a suggestion,You can do any chapter inbetween but in my opinion you should go with the flow to understand completely every chapter plus it will help you to better understanding.
