is this a good answer?

Answer 3

can you make a drawing please?

Answer 4

1. opposite angles are equal (vertical angles) ex. 1 and 3 and 2 and 4 2. two adjacent angles add to 180. Ex. 60 and 120.

Answer 5

in this case we can write:
\[\widehat A = \widehat B\]

Answer 6

ok but is my answer correct?
1. opposite angles are equal (vertical angles) ex. 1 and 3 and 2 and 4 2. two adjacent angles add to 180. Ex. 60 and 120.

Answer 7

furthermore this relation:
\[180 - \widehat A + \widehat B = 180\]
also holds
yes! I think it is correct!
