No two sides of a triangle can ever be parallel.
Like all other triangles it has no parallel lines.
There cannot be parallel lines in any [plane] triangles.
A triangle can't have.
There are no parallel lines in a triangle.

Three pairs. The line joining the midpoints of any two sides of a triangle is always parallel to the third side of the triangle (and half its length).
Like all other triangles it has no parallel lines.
The perpendicular adjacent sides in the triangle would be 3 sides. It is the basically horizonstal line next to a vertical line(perpendicular) if it was parallel adjacent then only two side of triangle /\ <-- parallel

There are no parallel sides in a right angle triangle
Any polygon, other than a triangle, can have a pair (or more) of parallel lines.
There are no parallel lines in any triangle but a right angle triangle has perpendicular line that meet each other at 90 degrees.
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.
Given a triangle and a line, if the line passes through two sides of the triangle parallel to the third side, then it cuts the sides proportionally.l
