Q1 Two parallel lines are cut by a transversal. If the corresponding angle is 52°, what is angle x?
Corresponding angles are equal
x = 52°
Q2 Find the co-interior angle if one angle is 56°.
Co-interior angles sum to 180°
x = 180° − 56° = 124°
Q3 The alternate angle is 137°. Find angle y.
Alternate angles are equal (Z-shape)
y = 137°
Q4 Angle a = 113°. Find the co-interior angle b.
Co-interior angles sum to 180°
b = 180° − 113° = 67°

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.
