Perpendicular lines meet at a right angle so a right angled triangle has two lines which are perpendicular to eachother. However there are no parallel lines in a right angled triangle, or any triangles for that matter.
A regular pentagon does not have parallel or perpendicular lines. Some other possibilities include, but are not limited to:a circlean ovalan equilateral triangle or any triangle that is not a right triangle.(A right angle's lines are perpendicular. Those are what make it a 90 degree angle.)
There cannot be parallel lines in any [plane] triangles.
There are absolutely 0 parallel lines in any given triangle.
A right angle triangle has no parallel sides
There are no parallel lines in any triangle but a right angle triangle has perpendicular line that meet each other at 90 degrees.
Perpendicular lines meet at a right angle so a right angled triangle has two lines which are perpendicular to eachother. However there are no parallel lines in a right angled triangle, or any triangles for that matter.
None of the sides of any triangle are parallel. However, you can draw an infinite number of parallel lines inside any triangle.

A triangle can never have any parallel sides.

The parallel sides of a polygon are sides that are segments of parallel lines. A polygon need not have any parallel lines. A triangle, for example, is a polygon that cannot have parallel lines.
A triangle cannot have any parallel sides.
No. it is the only polygon that can not have parallel lines all though any regular polygon with an odd number of lines will have no parallel lines If three points were in a straight line it could be argued that these formed a triangle with parallel sides, though really it would be just a line; or if we had a triangle with infinite height the sides would be parallel. In any other case, no.
A right angle triangle has no parallel sides
