Answer:
Option (1)
Explanation:
From the picture attached,
Lines 'm' and 'n' are the parallel lines and 'r' is a transversal line intersecting these lines at two distinct points.
Therefore, both the angles will be congruent by the property of corresponding angles postulate.
By the converse of corresponding angles postulate,
If these angles are congruent then both the lines (m║n) will be parallel.
Option (1) will be the answer.
