Question

Pls give step by step explanation. I will mark him/ her as brainliast. but pls give answer fast. By explanation.​

Answer 1

Answer:

Mark as Brainliest

Step-by-step explanation:

In triangles ADC and CBA, we have

AB=CD(given);

AD=BC(given);

AC=AC(common side).

By S.S.S congruency condition,  

△ADC≅△CBA Hence proved

Answer 2

Answer:

in ∆ ADC & ∆ CBA ,

AB = CD (given)

AD = CB (given)

AC = CA (common)

so, ∆ADC congruent to ∆CBA (SSS)
