shape no pairs of perpendicular sides
I suppose. All of a square's sides are perpendicular.
A polygon with only 1 pair of perpendicular sides is called a trapezoid. In a trapezoid, one pair of opposite sides are parallel, while the other pair are not parallel and intersect at a right angle. The sum of the interior angles of a trapezoid is always 360 degrees. Examples of trapezoids include isosceles trapezoids, right trapezoids, and scalene trapezoids.
A triangle has no parallel sides but a right angle triangle has perpendicular sides that meet at 90 degrees.
trapezium
The first geometric shape that comes to mind with no perpendicular sides is a triangle.
Any shape, other than a triangle can have a pair of perpendicular sides.
A square or a rectangle has perpendicular sides that meet each other at right angles which is 90 degrees.
The question contradicts itself. A dodecagon need not have any perpendicular sides.

No but its diagonals are perpendicular
No not normally
A right angle has one pair of perpendicular sides.
Square, rectangle and ovals.
Put 2 lines on the perpendicular sides and put 1 line for the parallel sides
The sides perpendicular to each other are at right angles (90 degrees, or square) to each other. An example of a figure with two pair of perpendicular sides is the rectangle.
