AA = angle angle, it means that the triangles have two of their angles equal.
We have no information about the angles
So
by AA = NO
SAS = Side, Angle , side
we know that two pairs of sides have the same ratio and the included angles are equal.
We have no information about the angles
So, SAS : NO
SSS= side ,side ,side
If 2 triangles have 3 pairs of sides of the same ratio.
6:3 = 2
9:7 = 1.2
9:7= 1.2
SSS: no
Answer : NONE
