By definition, perpendicular lines form right angles.
always 90 degrees
sometimes
yes, because perpendicular lines always intersect. all lines intersect unless they are parallel or on separate planes (skew)
Yes they are.
Sometimes.Perpendicular lines always intersect.Parallel lines never intersect.Therefore, intersecting lines may be perpendicular, but not always.
A rectangle's perpendicular lines are ALWAYS adjacent to eachother
Any polygon with four or more sides can have perpendicular and parallel lines.
perpendicular lines always form a right angle
Yes, perpendicular lines always cross to form two right angles.
Lines that always form right angles when they meet are perpendicular lines. The first line is perpendicular to a second line.
Yes
Perpendicular lines always intersect and make 90 degree angles. Parallel lines never intersect with each other.
Yes they always do! They are not Perpendicular if they don't.
Negative reciprocal slopes always represent perpendicular lines.
By definition, perpendicular lines form right angles.
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.
