Answer:
Some of them are wrong
Explanation:
The revisions I made are in BOLD and underlined.
∠1 and ∠4 are vertical angles
∠1 and ∠2 are obtuse angles because they are angles that measure between
90° and 180°.
∠3 and ∠4 are adjacent angles because they have a common vertex.
∠4 and ∠5 are supplementary because they lie on a straight line and have a sum of 180°.
