Explanation:

Step1: Vertical angles

Vertical angles are equal. Angle 4 and angle 1 are vertical angles. So, $\angle1=\angle4 = 70^{\circ}$.

Step2: Alternate interior angles

When two parallel lines are cut by a transversal, alternate - interior angles are equal. Angle 4 and angle 5 are alternate - interior angles. So, $\angle4=\angle5 = 70^{\circ}$.

Step3: Corresponding angles

When two parallel lines are cut by a transversal, corresponding angles are equal. Angle 4 and angle 6 are corresponding angles. So, $\angle4=\angle6 = 70^{\circ}$.

Answer:

1, 5, 6
