A right trapezoid has exactly one pair of perpendicular lines and is a quadrilateral.
Draw a right angle corner, then add 4 more sides that are NOT right angles...

The question contradicts itself. A dodecagon need not have any perpendicular sides.
a trapazoid
shape no pairs of perpendicular sides

Draw a right angle corner, then add 4 more sides that are NOT right angles...
The first geometric shape that comes to mind with no perpendicular sides is a triangle.
