A right angle has one pair of perpendicular sides.
Any shape, other than a triangle can have a pair of perpendicular sides.
Hexagon.
No unless it is in the form of a rectangle
trapazoid
An irregular hexagon.
Yes, they can exist.
Well, isn't that just a happy little shape! When you have a hexagon with exactly one pair of perpendicular sides, you have a special hexagon called a "rectangular hexagon." It's like nature decided to add a little twist to the usual hexagon shape, creating something unique and beautiful. Just remember, in the world of shapes, there's always room for a little bit of creativity and surprise!
a trapazoid
A hexagon with only one pair of parellel sides
The question contradicts itself. A dodecagon need not have any perpendicular sides.
shape no pairs of perpendicular sides
A right trapezoid has exactly one pair of perpendicular lines and is a quadrilateral.
It is possible for a hexagon to have one pair of parallel sides. A hexagon can have 0, 1, 2 or 3 pairs of parallel sides, and can have 0, 2, 3, 4, 5, or 6 parallel sides.
I suppose. All of a square's sides are perpendicular.
No but its diagonals are perpendicular
a pentagon
