Answer:
There is not enough information to say.
Explanation:

In order to be congruent triangles following axioms should need to be fulfilled.
SSS (Side-Side-Side): Two triangles are congruent if all three pairs of corresponding sides are equal.
SAS (Side-Angle-Side): Two triangles are congruent if two pairs of corresponding sides and the included angle between them are equal.
ASA (Angle-Side-Angle): Two triangles are congruent if two pairs of corresponding angles and the included side between them are equal.
AAS (Angle-Angle-Side): Two triangles are congruent if two pairs of corresponding angles and one pair of corresponding sides (not between the angles) are equal.
HL (Hypotenuse-Leg): In right triangles, two triangles are congruent if the hypotenuse and a leg of one triangle are equal to the hypotenuse and a leg of the other triangle.
These axioms can be used to prove that two triangles are congruent.

For the question:
Since two side are given, we need one more side or angle to say that they are similar,
So, the answer is:
There is not enough information to say.
