If angle a is congruent to itself by the reflexive property, which transformation could be used to prove δabc ~ δade by aa similarity postulate?

triangles abc and ade, in which point b is between points a and d and point c is between points a and e

translate triangle abc so that point b lies on point e to confirm ∠b ≅ ∠e.
translate triangle abc so that point c lies on point e to confirm ∠c ≅ ∠e.
dilate δabc from point a by the ratio segment ad over segment ab to confirm segment ad ~ segment ab.
dilate δabc from point a by the ratio segment ae over segment ac to confirm segment ae ~ segment ac.
