Which theorem or postulate justifies that angle hef~angle hge ?

a. aa similarity postulate
b. sas similarity theorem
c. sss similarity theorem
d. ssa similarity theorem

I think the correct answer from the choices listed above is option A. The postulate the justifies that HEF = HGE would be the AAA similarity postulate. It states that two triangles have their corresponding angles equal if and only if their corresponding sides are proportional.
