Question

Question:-

In the given figure, AB perpendicular to BD, CD perpendicular to BD and AB = CD.

Prove that:-

(i) ∆ABD = ∆CDB

(ii) AD=CB

​​

Answer 1

Answer:

(I) triangle of abd =triangle of cdb

Answer 2

Answer:

∆ABD = ∆CBD

Step-by-step explanation:

In ∆ABD = ∆CDB

AB = CD ( given )

Angle ABD = Angle CDB = 90°

BD = DB ( common )

hence , ∆ABD = ∆CDB ( SAS congruence rule or congruence criteria)
