Let's copy the diagram and mark the angles we are asked to compare.
We can see that two sides of △ ABC are congruent to two sides of △ DEF. However, the third side of △ ABC is longer than the third side of △ DEF.
AB&≅DE
BC&≅EF
CA&> FD
According to the Converse of the Hinge Theorem, the included angle measure in △ ABC is greater than the included angle measure in △ DEF.
m∠ ABC> m∠ DEF
