Determine whether the two triangles are congruent. If they are congruent, state by what theorem (SSS, SAS, or ASA) they are congruent. Let a = 111, c = 39, x = 7, d = 111, f = 39, and y = 7. a. Yes, the two triangles are congruent by the SSS Theorem.
b. Yes, the two triangles are congruent by the SAS Theorem.
c. Yes, the two triangles are congruent by the ASA Theorem.
d. No, the two triangles are not congruent.
