Congruent triangles
We know that two triangles have the same three components they are probably congruent:
For right triangles:
If we know that two of their same sides are equal, then they are congruent.
There are two groups of three data that are not enough to know if two triangles are equal:
In this question we have that the criteria shown is:
(1). ASA
(2). Right triangles with same sides
(3). SSA
(4). SSS
We are looking for a pair of triangles that has SSA or AAA information, since it is not enough information to know if they are congruent (3 figure).
The only one is (3).
Answer - the third 3 picture does not contain enough information to know if the triangles are congruent
