A square and a rectangle because their corners meet at 90 degrees
I suppose. All of a square's sides are perpendicular.
Yes.

Any shape, other than a triangle can have a pair of perpendicular sides.

trapezoid
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.
The question contradicts itself. A dodecagon need not have any perpendicular sides.
It could be a right angle triangle
shape no pairs of perpendicular sides
Yes it does. Do you even know what perpendicular means? It means that two sides can keep going but never touch. If you look at a prism depending on what prism it is it should have at least one pair of perpendicular sides.
