    \(\triangle ABC \) and \(\triangle A'B'C'\) such that AB = A'B', AC = A'C', BC = B'C'. Prove that \(\triangle ABC \cong \triangle A'B'C'\)

    SSS is a postulate

    right, I don't think you prove this one. It would be like proving The Axiom of Choice without one of its equivalents.

    @oldrin.bataku @zzr0ck3r , this course is modern geometry. We learn how to prove a theorem (and SSS is a theorem, not postulate). The course is to train high school teacher how to teach geometry.

    ahh, I never took geometry but when I googled it, it seemed like it was not something you prove.

    SSS is a postulate in the original formulation of Euclidean geometry: https://en.wikipedia.org/wiki/SSS_postulate depending on what alternative axiomatization you use for your modern geometry course, sure, you can prove it from that alternative foundation, but without stating that before it is only natural to assume we're talking about classical Euclidean geometry. it is impossible to even answer your question without your axiomatization anyways so this question as it stands is ill-posed and impossible to answer
