<u>Step-by-step explanation:</u>
→ ∠CEA and ∠CEF share a common side so they are adjacent

→ ∠FEB and ∠BED share a common side so they are adjacent.
→ The sum of their angles is 90° so they are complimentary.
The sum of their angles is not 180° so they are not supplementary. They are not across from each other so they are not vertical.
