Which statement is demonstrated by this construction?
(1) If a line is parallel to a line that is perpendicular to a third line,
then the line is also perpendicular to the third line.

The set ofpoints equidistant from the endpOints of a line segment
- is the perpendicular bisector of the segment.
(3) Two lines are perpendicular if they are equidistant from a given
point.
(4) Two lines are perpendicular if they intersect to form a vertical line.
