If δmnl is rotated 180° about point n, 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.
reflect onp over line k.
reflect m'n'l' over line k.
dilate onp from point n by a scale factor of segment np over segment nl.
dilate m'n'l' from point n by a scale factor of segment np over segment nl
