Answer:
The vertical angles are angle AFE and angle BFD ⇒ 1st answer
Step-by-step explanation:
* Lets explain when the vertical angle are formed
- The vertical angle are formed wen two lines cross each other
- The vertical angles are opposite to each other
- The vertical angles are equal in measures
* Look to the attached figure
- There are three lines intersected at point F, line AD , line BE and
line FC
- Line AD intersects line BE at F
- Line FC intersects the two lines at F, where FC is between the sides
of the angle BFD
- Lets find the vertical angles
∵ Line AD intersects line BE at F
∴ ∠ AFE and ∠ BFD are vertical angles
∴ ∠ AFB and ∠DFE are vertical angles
∵ Line FC intersects the two lines AD and BE at point F
∵ The end point of line FC is F
∴ There is no vertical angles formed between the two lines and the
line FC
∴ The vertical angles are angle AFE and angle BFD
