Step-by-step explanation:

use the sas triangle congruency theorem

step-by-step explanation:

the sas triangle congruency theorem states that "if two sides and the included angle of one triangle are congruent to two sides and the included angle of another triangle, then these two triangles are congruent." in your case, the two sides ed and df are congruent to ab and ac respectively, and the included angles a and d are also congruent. thus, you can use the sas triangle congruency theorem to prove that they are congruent.
