Question

3. In adjacent figure AB = CD and AD = BC then answer the following:
(i) How many triangles are there in the figure.
(ii) Prove that AABD=ACDB by giving the 3 matching parts. State the congruence condition also.
(iii) Is ZA = ZC? Give reason.
✨ Please answer briefly✨ ​

Answer 1

Step-by-step explanation:

In △ABD and △CDB

AB=CD (given)

∠ABD=∠CDB (given)

BD=DB (common side)

∴△ADB≅△CDB by SAS criteria.

So option A is correct
