Answer:
They have the same angles.
Explanation:
In order for two triangles where you know the side lengths to be congruent, their sides must be in the same ratio at all times. If this s not satisfied, they are not similar. This means that KJ / RS = KL / TS = JL / RT, or 15 / 12 = 20 / 16 = 25 / 20, or 5/4 = 5/4 = 5/4. This means that the two triangles are similar.
Finally, this implies that they have the same angles.
