Ellie drew δlmn, in which m∠lmn = 90°. she then drew δpqr, which was a dilation of δlmn by a scale factor of one half from the center of dilation at point m. which of these can be used to prove δlmn ~ δpqr by the aa similarity postulate?

m∠p ≅ m∠l; this can be confirmed by translating point p to point l.

m∠p ≅ m∠n; this can be confirmed by translating point p to point n.

segment lm = one halfsegment pq; this can be confirmed by translating point p to point l.

segment mn = one halfsegment qr; this can be confirmed by translating point r to point n.
