No, in Euclidean geometry they do not meet.
Because of the way parallel lines are defined. Parallel lines never meet, but to qualify as parallel lines, additional conditions may apply. From Wikipedia: "Two lines in a plane that do not intersect or meet are called parallel lines." Emphasis added.
Perpendicular is when a line is at a right angle to another. Parallel lines are side by side and even if they were to go on to infinity, would never meet. Therefore the answer is perpendicular.

Perpendicular
No, parallel lines do not meet at a right angle. In theory, parallel lines never meet. In practice, parallel lines on earth could meet at the North Pole and/or the South Pole. Perpendicular lines meet at a right angle.
An angle is formed where two lines meet. Parallel lines do not meet. Therefore they do not form an angle. So there is no angle to have a name. So no name.
A right angle has no parallel lines, but it does have perpendicular lines that meet at right angles.
Parallel lines do not meet and so cannot form an angle.
An angle has lines that meet at the angle end, but that stretch apart at the other end. Parallel lines are like railway lines. They go on and on and never meet.
No, in Euclidean geometry they do not meet.
No because parallel lines remain equal distance apart and never intersect with each other.
There are no parallel lines in any triangle but a right angle triangle has perpendicular line that meet each other at 90 degrees.
No, perpendicular lines are lines which intersect (cross each other/meet) and a 90 degree angle, while parallel lines a lines which run along side each other and will never intersect/meet.
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. A triangle can never have parallel lines. Parallel lines run alongside each other, so that if they continued forever, they would never meet, such as the top and bottom of a square. All lines meet in a triangle. A right triangle is distinguished by having one 90 degree angle (also known as a right angle).
Parallel lines meet in infinity(they don't meet at all)
