just see if its a right angle

perpendicular.
Lines that aren't perpendicular
PERPENDICULAR
Octagons have no perpendicular lines.
= parallel + perpendicular As such no, perpendicular lines do not naturally have parallel lines. However...connect the lines in the symbols below. ++ ++ And you'll have 4 perpendicular lines, and 4 parallel lines.
Perpendicular lines intersect.

Lines that intersect at 90 degrees are perpendicular lines
A rhombus has parallel lines but no perpendicular lines.
Octagons have no perpendicular lines.
I believe they do, and they have 2 perpendicular lines.
By definition, perpendicular lines are those which meet in a right angle. So, yes, they have to meet in order to be "perpendicular". Parallel lines may, or may not, meet, depending on how you choose your axioms. In Euclidean geometry, parallel lines never meet. In certain types of non-Euclidean geometry, they can meet.
No. If the lines are parallel they will never meet or intersect at any point. If the lines are perpendicular they do intersect, but perpendicular lines are a special case of intersecting lines. Perpendicular lines are exactly 90 degrees from each other. Intersecting lines do not haveto be perpendicular... but perpendicular lines are always intersecting.
