Side AB = 5, side BC = 6, side DE = 5, and side EF = 6. What additional information would you need to prove that ΔABC≅ΔDEF by SSS?

1.Side AC is congruent to side DF.
2.Side AC is congruent to side FE.
3.Side BC is congruent to side DE.
4.Side BC is congruent to side ED.



Respuesta :

well you are missing one side of the triangle from each.  In the first one you are missing the side AC and the second one you are missing the side DF.  So to prove that they are congruent by SSS you need that AC is congruent to DF
