Answer 1

sorry idk

Answer 2

So the order matters.
ITH = APG
THi = PGA
HIT = GAP
ONLY!!! See how I only switched the letters around by the same position for each?

Now you need to find the one that matches the arrangement.
The first one is NO because IH matches with AG
The second one makes sense since it follows the arrangement
The third one is NO because ITH matches APG
and IT matches AP not GA

Answer 3

I'd suggest you draw both triangles and label them. Then comparisons would be easier.
