Question

In the given figure, triangles ABC and ABD are congruent by congruence criterion​

Answer 1

Answer:

SAS congruence criterion.

Step-by-step explanation:

in ∆ ABC and ∆ ABD, AB is the common side

AC = AD = 5cm

and angle DAB = angle CAB = 30⁰

therefore, ∆ABC is congruent to ∆ ABD [by SAS congruency]

the [ ] is the answer to your question and the whole step-by-step explanation is how it is proved.

Hope this helps you. Have an excellent day ahead
