A polygon with four or more sides can meet these requirement.
shape no pairs of perpendicular sides
a Kite
a cross
Square
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
trapazoid
shape no pairs of perpendicular sides
trapezoid
square
It could be a right angle triangle
a Kite
No anwser impossible
A hexagon.
parallelogram
For a shape to have parallel sides it needs at least 4 sides
Hexagon.
A shape that has two parallel lines and no perpendicular lines is a trapezoid, specifically an isosceles trapezoid. In this shape, one pair of opposite sides is parallel, while the other pair is not perpendicular to the parallel sides. This creates a unique geometry without right angles. Another example could be a parallelogram, which also has two pairs of parallel sides but does not necessarily have any perpendicular lines.
