I suppose. All of a square's sides are perpendicular.
a square
shape no pairs of perpendicular sides
Any polygon can have only 1 pair of perpendicular sides.
Every quadrilateral that is a standard square, rectangle, or parallelogram has at least ONE pair of parallel sides - and they all have two pairs of parallel sides. For only ONE pair of parallel sides, you need an irregular trapezoid.
A triangle has no parallel sides but a right angle triangle has perpendicular sides that meet at 90 degrees.
Any shape, other than a triangle can have a pair of perpendicular sides.
Yes.
A square and a rectangle because their corners meet at 90 degrees
trapazoid

a trapazoid
trapezoid
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.
The question contradicts itself. A dodecagon need not have any perpendicular sides.
It could be a right angle triangle
a square
shape no pairs of perpendicular sides
