Which method and additional information would prove ΔONP and ΔMNL similar by the AA similarity postulate? Use rigid and nonrigid transformations to prove segment PN over segment MN = segment LN over segment ON. Use a rigid transformation to prove that ∠NPO ≅ ∠NLM. Use rigid and nonrigid transformations to prove segment PN over segment ML = segment LN over segment ON. Use a rigid transformation to prove that ∠NLM ≅ ∠LMN.
