Answer:

Δ ABC ≅ Δ LMN

Explanation:

To determine if 2 triangles are congruent by side- angle- side postulate SAS)

We require

corresponding side - corresponding angle - corresponding side to be congruent ( equal )

From the diagram

the only figures with 2 sides and included angle ( angle between 2 sides ) is the first and third.

AC = LN ( single dash through them )

∠ C = ∠ N ( both have the same arc at the vertex )

BC = MN ( double dash through them )

Then

Δ ABC and Δ LMN are congruent by the SAS postulate
