Answer:
The correct options are B and D:
B) SOE and DOA
D) EOA and DOS
Explanation:
Vertical angles can be defined as those angles which are formed opposite to each other when two line are crossed. These angle have a common vertex. Vertical angles are always equal to each other.
Considering option A, <SOB and <AOB are not vertical angles as they are not opposite to each other.
Considering option B, <SOE and <DOA are vertical angles as they are opposite to each other.
Considering option C, <BOA and <BOE are not vertical angles as they are not opposite to each other.
Considering option D, <EOA and <DOS are vertical angles as they are opposite to each other.
