The question consists of two statements, namely, Assertion (A) and Reason (R). Please select the correct answer.


Assertion (A)



Reason (R)



∆ABC and ∆DBC are two isosceles triangles on the same base BC. Then, ABD=ACD.




The angles opposite to equal sides of a triangle are equal.


Since, angles opposite to equal sides are equal

AB = AC


ABC = ACB (i)


DB = DC


DBC = DCB (ii)


Subtracting (ii) from (i),


ABC - DBC = ACB - DCB


Hence, the assertion is true and also the reason gives the right explanation of the assertion.


Option A is correct
