Which method and additional information would prove δonp and δmnl 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. use a rigid transformation to prove ∠nop ≅ ∠nml. use a rigid transformation to prove ∠nop ≅ ∠onp. use rigid and nonrigid transformations to prove segment ln over segment on = segment pn over segment mn. use rigid and nonrigid transformations to prove segment lm over segment on = segment pn over segment mn.
