Concept:In congruent triangles, the order of vertices tells which sides match.Explanation:We are given three equal side pairs: ∣XZ∣=∣MN∣, ∣ZY∣=∣MO∣, and ∣XY∣=∣NO∣.Since ∣XY∣=∣NO∣, the side XY matches side NO.Since ∣ZY∣=∣MO∣, the side ZY matches side MO.Since ∣XZ∣=∣MN∣, the side XZ matches side MN.So the vertex correspondence is X↔N, Y↔O, and Z↔M.Therefore, the ordered matching is △XYZ≅△NOM.Answer:D. △XYZ=△NOM
