Yes — choose: "Yes, they are congruent by either ASA or AAS."

Reason: LN is the perpendicular bisector of MQ, so N is the midpoint (MN = NQ) and LN ⟂ MQ, hence ∠MNL = ∠QNL = 90°. Given ∠LMN = 58°, the third angle in ΔMNL is 180 − 90 − 58 = 32°, so ∠MLN = 32°, which equals the given ∠NLQ. Thus each triangle has ∠N = 90°, ∠L = 32°, and they share side NL between those angles, so the triangles are congruent (ASA; AAS also applies).
