Triangle X has angles of $50^\circ$ and $60^\circ$. Triangle Y has angles of $50^\circ$ and $80^\circ$. Are the two triangles similar?

Yes, they both have a $50^\circ$ angle.

No, their third angles do not match.

Yes, because the sum of their angles is $180^\circ$.

Not enough information is given.
