For congruent triangles, the corresponding parts are sides and angles. Using the congruence statement that \(\displaystyle△{A}{B}{C}≅△{D}{E}{F}\), we can write the following by using corresponding vertices (or letters from the statement):

\(\displaystyle∠{A}≅∠{D},∠{B}≅∠{E},∠{A}≅∠{D}\)

\(\displaystyle{A}{B}¯¯¯¯¯≅{D}{E}¯¯¯¯¯,{B}{C}¯¯¯¯¯≅{E}{F}¯¯¯¯¯,{A}{C}¯¯¯¯¯≅{D}{F}¯¯¯¯¯\)

\(\displaystyle∠{A}≅∠{D},∠{B}≅∠{E},∠{A}≅∠{D}\)

\(\displaystyle{A}{B}¯¯¯¯¯≅{D}{E}¯¯¯¯¯,{B}{C}¯¯¯¯¯≅{E}{F}¯¯¯¯¯,{A}{C}¯¯¯¯¯≅{D}{F}¯¯¯¯¯\)
