Congruent triangles have what property in common?

Explanation:
Congruent triangles are identical in size and shape, so every corresponding part matches exactly. That means the sides of one triangle have the same lengths as the sides of the other, and the angles have the same measures. Among the options, having the same side lengths is the defining feature because it ensures the triangles are a perfect copy of each other when aligned. Equal angles alone can occur in similar triangles that differ in size, and equal areas or equal perimeters can happen for non-congruent triangles as well. So the best answer is that they have the same side lengths.
