Sandra knows that the corresponding angles of two triangles are congruent. She claims that the two triangles must be congruent. Do you support or refute her claim? Why?

A
Helga is correct since three angles determine one unique triangle, so the two triangles must be congruent.

B
Helga is incorrect since the two triangles must also have congruent corresponding sides to be congruent.

C
Helga is correct since all that is needed to prove that triangles are congruent are two corresponding angles.

D
Helga is incorrect since only similar triangles, but not congruent triangles, have congruent corresponding angles.
