Question

1. R , S, and T are the vertices of one triangle. E, F, and D are the vertices of another triangle. mR = 60, mS = 80, mF = 60, mD = 40, RS = 4, and EF = 4. Are the two triangles congruent? If yes, explain and tell which segment is congruent to . (1 point)yes, by ASA;
yes, by AAS;
yes, by SAS;
No, the triangles are not congruent
