Answer 2

Answer:

Step-by-step explanation:

As it is c rhombus

so all the sides will

be equal

and 1/5 △ADC and △ABC are congruent.

∠BAC=∠CAD

∠DCA=∠BCA

AC → common in both triangle

So it congruent by ASA (Angle side angle criteria)

Similarly △ABD  and △BCD

are congruent

by ASA criteria

DB→ common side

∠ADB=∠CDB

∠ABD=∠CBD
