The question contradicts itself. A dodecagon need not have any perpendicular sides.
The only requirement for a trapezoid is that one pair of opposite sides be parallel. There could be trapezoids with a pair of perpendicular lines.

An irregular hexagon.
A dodecagon has 12 sides. A polygon with 13 sides is a triskaidecagon.
shape no pairs of perpendicular sides
I suppose. All of a square's sides are perpendicular.
No but its diagonals are perpendicular
No not normally
A right angle has one pair of perpendicular sides.
The first geometric shape that comes to mind with no perpendicular sides is a triangle.
The only requirement for a trapezoid is that one pair of opposite sides be parallel. There could be trapezoids with a pair of perpendicular lines.
There are 10 sides to a dodecagon and there are 12 sides on a dodecahedron. * * * * * There are, actually 12 sides to a dodecagon, not 10.
Any shape, other than a triangle can have a pair of perpendicular sides.
A dodecagon has 12 sides.
a dodecagon does have 12 sides
A dodecagon has 12 sides
