Answer:

The statement is true is  CF Perpendicular AE .

Option (d) is correct.

Step-by-step explanation:

As given

∠AFC = ∠EFC

Let us assume that the measure of ∠AFC be x.

Thus

∠AFC = ∠EFC = x

As

∠AFC + ∠EFC =  180°  (By Linear pair property)

x + x = 180°

2x = 180°

[tex]x = \frac{180}{2}[/tex]

x = 90°

Thus

∠AFC = ∠EFC = 90°

Therefore CF is perpendicular to AE .

Option (d) is correct.
