Question

3 lines are shown. A line with points A, F, D intersects with a line with points B, F, E at point F. Another line extends from point F to point C in between angle B F D. Which are vertical angles? AngleAFE and AngleBFD AngleBFC and AngleDFE AngleAFE and AngleCFD AngleBFC and AngleEFA

Answer 1

The first answer

Explanation:

Answer 2

The vertical angles are angle AFE and angle BFD ⇒ 1st answer

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
