Is △NTM ≅ △SMT? Explain.

• Yes; NT ≅ SM, ∠NTM = ∠SMT, and MT ≅ TM, so the triangles are congruent by Side-Angle-Side.

• Yes; NT ≅ SM, MT ≅ TM, and ∠NTM = ∠SMT, so the triangles are congruent by Side-Side-Angle.

• Yes; the triangles are right triangles, NT ≅ SM, and MT ≅ TM, so the triangles are congruent by Hypotenuse-Leg.

• No; the triangles are not congruent.
