Given : ABC is an isosceles triangle in which AB = AC. BE and CF are its two medians.  

 

To prove: BE = CF

Proof:

In ∆ABC, it is given that  

AB = AC  

∠B = ∠C ………….(1)

[Angle opposite to equal sides are equal]

Again , AB = AC  

½ AB = ½ AC  

BF = CE …………(2)

[∵ E & F the midpoints of AC and AB]

In ∆ BEC & CFB ,  

CE = BF ( from eq 2)

∠B = ∠C  (from eq1)

BC = CB (Common)

Therefore, By SAS congruence criterion , we obtain ∆ BEC ≅ CFB.

BE = CF (By CPCT)
