Answer:
∠KLC is the alternate angle of ∠BKL
Explanation:
Alternate angles are angles that are opposite of one another and on two different parallel lines created by an intersecting line (also known as a transverse line).
In this case, the parallel lines are lines A↔B and C↔D, and the transverse line is M↔N. Therefore, the alternate angle from ∠BKL is ∠KLC.
