A triangle, no matter the type, can never have any parallel sides. To try this out, draw any two parallel lines on a sheet of paper and try to make a triangle out of it.
yes an arrowhead has 4sides because it is a quadrilateral but it doesn't have any parallel sides
A trapezium has just the 1 line of symmetry.
None.
