R, S, and T are the vertices of one triangle. E, F, and D are the vertices of another triangle, m/R = 60, m/S=80, m/F = 60, m/D = 40, RS 4, and EF = 4. Are the two = triangles congruent? If yes, explain and tell which segment is congruent to RT. yes, by AAS; ED O yes, by SAS; ED No, the two triangles are not congruent. yes, by ASA; FD
