Question: Which of the following triangles is congruent to triangle ABC if AB = 5, AC = 7, and BC = 5?

Options:

1. Triangle DEF with DE = 5, DF = 7, EF = 5
2. Triangle GHI with GH = 5, HI = 7, GI = 6
3. Triangle JKL with JK = 5, KL = 5, JL = 7
4. Triangle MNO with MN = 6, NO = 5, MO = 5

Correct Answer: Triangle DEF with DE = 5, DF = 7, EF = 5

Solution:

Triangles are congruent if they have the same side lengths. Triangle DEF has the same side lengths as triangle ABC.
