Question:-

The correct question is:-Prove that the bisectors of the base angles of an isosceles triangle are equal.

Step-by-step explanation:

solution:-

In △ABC,

AB=AC [Given]

∴∠C=∠B .....(i) [angles opp. to equal sides are equal]

⇒1/2<C = 1/2<B.

∠BCF=∠CBE.......(ii)

Now, In △BCE and △CBF,

=>∠C=∠B [From (i)]

=>∠BCF=∠CBE [From (ii)]

=>BC=BC [Common]

△BCE≅△CBF [AAS]

⇒BE=CF [cpct].
