Answer with explanation:
SSA=Side-Side-Angle
Following are Congruency Criterion of two Triangles
(a)SSS (b)SAS (c)AAS or ASA or SAA are same. (d)RHS
If you Know two sides of triangle ,and one angle which is not in between these two angles, then the two Triangles can't be congruent.By using Sine rule , you can find remaining Angles and sides.
Consider two triangles ABC and DEF in which
----- AB=DE
-----BC=EF
----- ∠C=∠F
If you will use sine rule in these triangles ,you will get angle A and angle C different from angle D and angle E.
But, if the third side of two triangles are same then the two triangles will be congruent by SSS,SAS or ASA.
So, we can conclude that, SSA is not a valid criterion for congruency of Triangles.
