D E and F are constructed to correspond with triangle ABC via "[i]Angle-Side-Side[/i]". In other words, they share two congruent sides and a non-included angle.[br][br]Angles [b]D[/b] and [b]A[/b] are congruent[br][br]Segments [b]DE[/b] and [b]AB[/b] are congruent[br][br]Segments [b]EF[/b] and [b]BC[/b] are congruent.
