Answer 5

first one

Answer 6

Okay, in this case dauspex's method works, because opposite angles are congruent in parallelograms. But it is not always so. For example:

Obviously there \(\widehat{DAB} \ncong \widehat{BCD}\).

P.S.: Sorry, I don't know how to make an arc accent, so I used `\widehat` instead.
