Question

in the given, triangle ABC and triangle DBC are both isosceles with a common base BC. the equal sides have been shown with similar markings if angle A = 60 and angle D= 40. find angle ABC and angle ACB , b). angle DBC and angle DCB. C). Angle ABD and angle ACD. Are these equal? ​

Answer 1

Answer:

ANSWER:

Yes.

In ΔABC and ΔDBCAB=DB (Given)AC=DC (Given)BC=BC (Common)By SSS criterion of congruency, ΔABC≅ΔDBC    

 

No, ∠ABD and∠ACD are not equal

because AB ≠ AC.
