Question

In the adjoining figure, AD = BC
and BD = AC. Prove that:
ADB =BCA
and DAB =CBA
Hint ABD =bac​

Answer 1

Answer:

In triangle ADB and triangle BCA 

AD=BC (GIVEN) 

DB=CA (GIVEN) 

angleDAB=angleABC (ANGLES OPPOSITE TO EQUAL SIDES ARE ALSO EQUAL) 

SO,TRIANGLE ADB CONGRUENT TO TRIANGLE BCA (SAS) 

SO,angle ADB=angleBCA (CPCT)

ALSO, angle DAB =angleCBA (CPCT)

hope it will help you
