which are vertical angles?\no ∠afe and ∠bfd\no ∠bfc and ∠dfe\no ∠afe and ∠cfd\no ∠bfc and ∠efa
Answer
Answer:
B. ∠BFC and ∠DFE
Explanation:
Step1: Recall vertical - angle definition
Vertical angles are formed when two lines intersect. They are non - adjacent angles opposite each other.
Step2: Analyze each option
- Option A: ∠AFE and ∠BFD are not vertical angles as they are not formed by the intersection of the same two lines in the correct non - adjacent, opposite manner.
- Option B: ∠BFC and ∠DFE are vertical angles. They are non - adjacent and formed by the intersection of lines EC and AD at point F.
- Option C: ∠AFE and ∠CFD are not vertical angles.
- Option D: ∠BFC and ∠EFA are not vertical angles.
