Question 519333
The method of proving something really depends on the question and what it's asking you to prove. Some proofs will be very straightforward and require only one theorem; others might be much trickier and require theorems from other areas of mathematics. You'll have to know the postulates and theorems, but proving something usually requires more than that.


Also, for which steps you're supposed to write next, I can't say much about that except that you should write your steps logically and in order.
