There cannot be parallel lines in any [plane] triangles.

An isosceles triangle has no parallel sides but 2 of its 3 sides are equal in length
Its a Right Triangle * * * * * No, a right triangle has only one pair of perpendicular lines. One possible answer is a kite, with right angles at the left and right extremes. There would be an obtuse apex and an acute bottom (or the other way around).
Nope think 2 parallel sides like this ______________ ______________ there would have to be another 2 lines..and we all know there are 3 lines in a triangle :)
There are no parallel sides in a right angle triangle
None !

2 paris of lines
never

A trapezoid has a pair of opposite parallel lines of different lengths A square has 2 pairs of opposite parallel lines of equal lengths A triangle has no parallel lines
All of the three sides of a triangle can be parts of parallel lines; it's just that no two of them can be parallel with each other. They can be parallel to some other line(s). In plane geometry parallel lines cannot form the sides of a common triangle.
A triangle has by definition three intersecting sides. If two of the sides are parallel, they will never intersect, so no triangle can ever be formed.
