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.
There are infinitely many possible answers. For example, any regular polygon with an even number of sides.
The question contradicts itself. A dodecagon need not have any perpendicular sides.
shape no pairs of perpendicular sides
I suppose. All of a square's sides are perpendicular.
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.
