Question

In the given figure , AD = CD and AB = CB. State three pairs of
equal parts in AABD and A CBD. Is A ABD = A CBD ? Give reason.​

Answer 1

i) AD=CD(given)

BC=AB(given)

DB=DB(common point)

ii) yes ABD=CBD,

Given=AD=CD

AB=CB

DB is the common line segment

To show=ABD=CDB

proof=a) AD=CD(Given)

BC=AB(Given)

DB=DB(Given)

b) so, using (a) part we can say that ABD is congruent to CBD (SSS Congruency rule)

=(is congruent to)
