To answer the question, let's begin by defining the term CPCTC. CPCTC is an abbreviation that stands for "Corresponding Parts of Congruent Triangles are Congruent".


\begin{gathered} \Delta ABC=\Delta DEF \\ |AB|\equiv|DE| \\ |BC|\equiv|EF| \\ |AC|\equiv|DF| \\ \angle A\equiv\angle D \\ \angle B\equiv\angle E \\ \angle C\equiv\angle F \end{gathered}

As such, options A, B, D are the correct answers
