Worked Example 1: Corresponding Angles

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
