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.
They both have at least one pair of parallel sides and at least one pair of sides of equal length.
Yes.
Any shape, other than a triangle can have a pair of perpendicular sides.
A square and a rectangle because their corners meet at 90 degrees

The question contradicts itself. A dodecagon need not have any perpendicular 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.

It could be a right angle triangle
