Parallel Lines and Transversal Review

Given the figure, which of the following are valid?

• Angle 2 is congruent to angle 4 because they are a linear pair

• Angle 5 is supplementary to angle 2 because they are corresponding angles

• Angle 6 is supplementary to angle 3 because they are same side exterior angles

• Angle 4 is congruent to angle 6 because they are corresponding angles

• Angle 2 is congruent to angle 1 because they are alternate interior angles
