Corresponding angles of ΔABC and ΔDEF are congruent. Does this prove that the triangles are congruent?
A) yes; AAA guarantees that all corresponding parts of the two triangles are congruent.
B) yes; AAA guarantees similarity and congruency because the triangles must have equal sides to have equal angles.
C) no; AAA only guarantees similarity because the lengths of the sides of the two triangles are not necessarily equal.
D) yes; AAA guarantees congruency because if at least two angles of a triangle are congruent to each other, then the triangles are congruent.
