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
A shape with a pair of perpendicular sides is a rectangle. In a rectangle, opposite sides are equal in length, and adjacent sides meet at right angles, forming perpendicular intersections. Other shapes that also feature perpendicular sides include squares and right triangles.
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.
Any shape, other than a triangle can have a pair of perpendicular sides.
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.
A dodecagon has 12 sides.
a dodecagon does have 12 sides
