Two parallel lines are cut by a transversal. One angle is 65°. Find the corresponding angle.
Step 1 Identify the relationship
Corresponding angles make an F-shape
They are in the same position at each intersection
Step 2 Apply the rule
Corresponding angles are EQUAL
Missing angle = 65°
Reason: Corresponding angles on parallel lines
