Answer:
AB = DE
BC = EF
CA = FD
Angle A = Angle D
Angle B = Angle E
Angle C = Angle F
(Of course Angle A is short for angle BAC, etc.)
If in triangles ABC and DEF, AB = DE, AC = DF, and angle A = angle D, then triangle ABC is congruent to triangle DEF.
Step-by-step explanation:
Again, one can make congruent copies of each triangle so that the copies share a side. Then one can see that AC must = DF.SSA would mean for example, that in triangles ABC and DEF, angle A = angle D, AB = DE, and BC = EF.
With these assumptions it is not true that triangle ABC is congruent to triangle DEF. In general there are two sets of congruent triangles with the same SSA data.
