If δonp is dilated from point n by a scale factor of segment nl over segment np, which additional transformation could determine if δonp and δmnl are similar by the aa similarity postulate?

segments om and lp intersect at point n; triangles are formed by points lnm and onp; line k intersects with both triangles at point n.

rotate o'n'p' 180° about point n.
rotate o'n'p' 90° clockwise about point n.
translate point p' to point m.
translate point o' to point l.
