Answer:

No

Explanation:

1) We need to use the AAA proof which states that any two triangles with all three angles congruent must also be similar.
2) We also need another rule that a triangle's angles must always add up to 180 degrees.

Using rule 2) we can find the third missing angle for the two triangles:

ABC:

180 - (60 + 79) = 41

DEF:
180- (60+ 42) = 78

We can now fill in that triangle ABC's angles are 60, 41, and 79

and

triangle DEF's angles are 60, 42, and 78

They are not the same, therefore the two triangles are not similar either, by rule 1).
