Answer: A. Yes
Step-by-step explanation: Two triangles are said to be congruent generally, if all sides of one triangle are equal to the corresponding sides of Another and the corresponding angles are equal.
But sometimes not enough information are given, and usually 3 out of the 6 sides and angles is enough to determine congruency.
No detail shows the angles are equal, but it can be deduced that the three sides corresponds (SSS). As such they'd make same and are therefore congruent.
