Perpendicular Lines. Quatr.us Math Geometry Lines. Perpendicular lines. Two lines are perpendicular if they cross at right angles. You can test this by extending the lines until they cross (if they do not cross then they are parallel).erpendicular Lines. Quatr.us Math Geometry Lines. Perpendicular lines. Two lines are perpendicular if they cross at right angles. You can test this by extending the lines until they cross (if they do not cross then they are parallel).
Perpendicular lines are two lines. that intersect to form right angles. The next three constructions involve constructing parallel. and perpendicular lines. Construction 5: Parallel through a Point Not on a Line. In this exercise we will construct a line parallel to a given line through a specific point not on. the line.
