Lalit Mehra sir,
u have used (C.P.C.T) in ur answer to Inshrah's question.
What is C.P.C.T ???????????????????
PLease answer as soon as possible.
Hi Meghana!
The word Corresponding Parts of Congruent Triangles is shortly represented as C.P.C.T.
This is a property for a pair of congruent triangles.
Consider a pair of congruent triangles ABC and PQR.

∆ABC ≅ ∆PQR
So, by using the property C.P.C.T. (Corresponding Parts of Congruent Triangles) it can be said that
AB = PQ, BC = QR, AC = PR, ∠ABC = ∠PQR, ∠BAC = ∠QPR, and ∠ACB = ∠PRQ
Hope! This will help you.
Cheers!!!
