The point
whatto line segments intersect but are not perpendicular
the parallel lines never intersect each other but they both intersect the line they are perpendicular to
Perpendicular lines intersect at right angles.
perpendicular
Yes, perpendicular lines do intersect at a single point. Think of the line representing the x-axis, and the line representing the y-axis. These two lines are perpendicular, and they intersect at the Origin (a single point).
It is a perpendicular line that intercepts another line at 90 degrees.
Perpendicular line
Perpendicular lines intersect at right angles. (90°) Therefore, by the definition of perpendicularity, two perpendicular lines must intersect.
Perpendicular line segments are line segments that intersect and make 90 degree angles.
They are mutually perpendicular. However, they need not intersect: if they are in different planes, they will not intersect.
90 degrees
perpendicular if they intersect at a 90 degree angle.
