No.
A triangle can't have.
No. A triangle contains three line segments.
A triangle has only three legs, none of which can be parallel. You may be thinking of a parallelogram.
NO !!! A triangle consists of three non-parallel lines.
A triangle cannot have two parallel sides. In order for a figure to be a triangle, it must be a closed figure with three sides and three angles. If two of the sides were parallel, there is no way the figure could be closed by only one other line.

No. A triangle contains three line segments.
The triangle midpoint theorem states that the line segment is parallel to the third side and is congruent to one half of the third side.

A trapezoid midsegment is parallel to the set of parallel lines in a trapezoid and is equal to the average of the lengths of the bases
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.
none, the three sides meet so there are no parallel sides but all the sides are equal.
If at least two of the three lines are parallel, the three lines will not form a triangle.

A triangle cannot be parallel because it is a polygon with three sides and three angles, while the concept of parallelism applies to lines. In geometry, two lines are defined as parallel if they never intersect and are always the same distance apart. Since a triangle consists of line segments (the sides) that connect at vertices, the sides can be parallel to other lines, but the triangle itself cannot be described as parallel.
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).
