yes perpendicular lines are at right angles to each other. Therefore they have to touch eventually
Perpendicular lines intersect each other at 90 degrees but parallel lines never touch each other
intersecting lines are alike because perpendicular lines have to intersect to be perpendicular. 2: They are the same because they touch another line so they are the same.
No
No, because although perpendicular and intersecting lines do touch, parallel lines never meet.
Yes, two perpendicular coplanar lines will touch. If you have two lines that, by definition, form a 90 degree angle (i.e., they are perpendicular) and are both on the same plane, eventually they must cross at some point on that plane. They will have exactly one point in common. If, however, the lines were, by definition, "perpendicular skew" lines, they would never cross because the definition forbids it.
If two lines are perpendicular, they intersect at a right angle. So yes, they will always cross each other.
No, because parallel lines will always go the same directions and never make a right angle.
They are not.
Two lines that are perpendicular to the same plane are coplanar. This means that they lay on the same plane.
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.
Actually it IS. perpendicular lines have opposite reciprocal slopes and parallel lines have the same slope.
