We got D is the midpoint of AC and BDC is congruent to BDA which both ar e given. We just need one more.
BD is common and equal in both of them .... secondly AD=DC since the two sides are equal in both the triangle ...and both are right angled ... thus .. hypotenuse must also be equal a result they are congruent by SSS property

oh okay thank you lots ;)
my pleasure :)
okay so you are sayin that AD=DC are SSS right? r are those two different things?
noooo .. they are the same .....AD = DC because .... d is the midpt ... sss means ... side side side property
that is all the three sides are equal
oh okay i get it now ;)
