In the given figure, is a cyclic quadrilateral whose sides and are produced to meet in

Prove that


In ΔEBC and ΔEDA,


∠EBC = ∠CDA


⇒ ∠EBC = ∠CDA ________________ (i)


∠ECB = ∠BAD


⇒ ∠ECB = ∠EAD ________________ (ii)


∠BEC = ∠DEA ________________ (iii)


From equation (i), (ii) and (iii),


ΔEBC ≅ ΔEDA Proved.
