Question

given that BD is the median of ABD and that ABD is isosceles congruence postulate SSS can be used to prove which of the following? (picture below )

Answer 1

correct answer is A. BAD=BCD

Answer 2

It is given in the question that

BD is the median. So it divides the opposite sides in two equal parts .

Therefore in triangles BAD and BCD,

AB and AC are congruent because of isosceles triangle.

AD and CD are congruent because of the median BD.

And BD and BD are congruent .

So the two triangles are congruent by SSS and the correct option is the first option .
