its not 2nd or 4th as they are already shown in the given figure

ganeshie8 · Answer

try if you can prove they are congruent by using any theorem ? (Leg hypotenuse  theorem?)

ganeshie8 · Answer

or SAS maybe

anonymous · Answer

I thought it was Triangle ABD is similar to triangle ACD.

ganeshie8 · Answer

similar triangles dont guarantee same side lengths

anonymous · Answer

Oh.. So it would be the first on because it's congruent

ganeshie8 · Answer

both above are similar triangles, but none of the sides are of  same length

ganeshie8 · Answer

yes you're right!
we can prove they are congruent, by using SAS
