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.

How many parallel lines can a triangle have?

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.


Does a right angled triangle have parallel lines?

No. Parallel lines are lines that extend in the same direction. In a triangle the lines go in different directions.


Two sides of a triangle are parallel?

No, Because the lines in a triangle meet, so they cant be parallel because parallel lines never meet.

It has no paralel lines. A paralel line are two lines that never cross. If you notice, in a trinagle all lines are touching all other lines.

Where are the parallel sides of a polygon?

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.


Can a triangle have the same perimeter and area as a parallelogram?

I don't know about the relation in the perimeters of a triangle and a parallelogram but if a triangle is on the same base on which the parallelogram is and the triangle is between the same parallel lines of the parallelogram, then the area of the triangle will be half the area of the parallelogram. That is, area of a triangle = 1/2 area of a parallelogram if the triangle is on the same base and between the same parallel lines.


Does a triangle have a set of parallel lines?

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.
