If all perpendicular lines are also intersecting lines, are all interesting lines also perpendicular lines? Explain, you'r answe
DerKrebs [107]

No.

However, for two lines to intersect, they do not necessarily have to intersect at a 90° angle.

<em>All perpendicular lines are intersecting lines, but not all intersecting lines are perpendicular.</em>
