choose the correct answer below.

c.

the asa postulate cannot be used to prove the congruence of the two triangles as shown because the triangles do not have two pairs of congruent angles.

d.

the asa postulate cannot be used to prove the congruence of the two triangles as shown because the included sides between the two pairs of congruent angles are not marked as congruent in both triangles.
