Two right-angled triangles with one pair of acute angles equal are —

aalways congruent
bsimilar
cequilateral

ব্যাখ্যা

Each triangle already has a $90°$ angle, and one pair of acute angles is equal; the third angles are then automatically equal. By the AAA criterion the triangles are similar (not necessarily congruent, since sizes may differ).
