Choose the postulate or theorem when combined with the aaa postulate for triangle similarity can be used to establish the aa postulate for triangle similarity?
a) sas postulate
b) asa postulate
c) angle sum theorem
d) angle bisector theorem

This is the concept of geometry, for us to prove the similarity of angles we can use the following postulates:
SAS (side-angle-side)
ASA (Angle side Angle)
SSS (side side side)
AAS (Angle Angle side)
therefore, given that AAA is used to prove similarity, another postulate that can be used to strengthen the postulate is SAS, because we already have the angle sizes, adding more sides will make the prove even stronger since we shall have three corresponding angles plus wo corresponding sides.
