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
Practice questions for Angles in Parallel Lines
Two parallel lines are cut by a transversal. Which statement about alternate angles is correct?
State the THREE angle rules that apply when a transversal crosses two parallel lines. For each rule, state whether the angles are equal or supplementary.
