In this figure, afc=efc. which statement must be true?

a) ad perpendicular eb
b) eb perpendicular ca
c) ad perpendicular ce
d) cf perpendicular ae

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°

x = 90°

Thus

∠AFC = ∠EFC = 90°

Therefore CF is perpendicular to AE .

Option (d) is correct.

all but the second one

step-by-step explanation:

cuz that one goes over 180
