The figure appears to be two triangles with its two sides coming from two intersecting lines.
By the symbol shown, it also appears that LM and PQ are parallel to each other.
With LM and PQ being parallel, we get:
Reason
∠L = ∠Q Alternate interior angles theorem
∠M = ∠P Alternate interior angles theorem
∠N = ∠N Vertical angles theorem
From this proof, we can say that Triangle LMN is similar to Triangle PQN.
Yes, they are similar, by AA Similarity.
