Name the construction.

• Angle bisector

• Perpendicular line to a point not on a line

• Angle median

• Perpendicular bisector of a line segment

• 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 traversal 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.
