Final answer:
Without additional context or a diagram, it is impossible to determine which angles are equal to 60° based on the information provided. Further clarification on the relationship between the given angles and ∠Alm or ∠m₁ is needed to identify congruent angles.
Step-by-step explanation:
We seem to have a misunderstanding in the question regarding the angles that are equal to 60°. Unfortunately, the information provided does not clearly link to the angles stated in the options a), b), c), and d), nor does it indicate a clear geometrical figure or relationship between the angles. Therefore, I'm unable to determine which angles are equal to 60° without more context or a diagram that shows the relationship between the given angles and ∠Alm or ∠m₁. However, for educational purposes, we can discuss identity or congruence of angles in general terms. If ∠m₁ is given as 60° and we are to find angles congruent to it, we would look for angles that may be defined as vertically opposite, corresponding, alternate interior, or angles that are involved in an isosceles triangle where the base angles are equal, for example.
