Which illustration shows the correct construction of an angle bisector?
Which geometric principle is used to justify the construction?
A line perpendicular to one of two parallel lines is perpendicular to the other.
Two lines are perpendicular if they intersect to form congruent adjacent angles.
When two lines are intersected by a transversal and alternate interior angles are congruent, the lines are parallel.
When two lines are intersected by a transversal and the corresponding angles are congruent, the lines are parallel.
