To prove that △AED ~ △ACB by SAS, Jose shows that AE/AC = AD/AB Jose also has to state that ∠A is congruent to ∠. A D ACB ABC

SAS Similarity. Side-angle-side similarity Triangles are similar if two sides in one triangle are in the same proportion to the corresponding sides in the other, and the included angle are equal . The given two triangles are similar  if their sides are in proportion and their included angle that is <A=<A of both the triangles also have the same value.measure.To prove that △AED ~ △ACB by SAS Jose also has to state that ∠A is congruent to ∠.A
