Correct Answer: (a) These have two equal sides and the same perimeter
Solution:If two sides of both triangle are equal and the perimeteris the same, the third side must also be equal because the perimeter is the sum of all sides.Therefore, all three sides of both triangle would be equal, satisfying the SSS (Side-Side-Side) congurence condition. So Option (a) is sufficient to conclude that the two triangles are congruent.
