Question

Zack notices that segment NM and segment PQ are congruent in the image below:

Two triangles are shown, NMO and PQR. N is at negative 3, 2. M is at negative 2, 0. O is at negative 1, 2. P is at 0, 0. Q is at 1, 2. R is at 2, 0. Angles M and Q are shown as congruent.
Which step could help him determine if ΔNMO ≅ΔPQR by SAS? (5 points)

segment MO ≅ segment QR

segment ON ≅ segment QP

∠ N ≅ ∠ R

∠ O ≅ ∠ Q

Answer 1

first of all do you know what mean this ,,SAS" ?
