The question contradicts itself. A dodecagon need not have any perpendicular sides.
A hexagon with only one pair of parellel sides
A trapezoid has only one pair of parallel sides. These parallel sides are opposite and are of different lengths.
Yes, an isosceles trapezoid has one pair of oppsite sides parallel and the pair of sides that are not parallel are equal.
Any shape with more than three sides can have a pair of parallel sides,but doesn't necessarily have.Every square, rectangle, rhombus, parallelogram, and trapezoid hasat least one pair of parallel sides.
trapezoid
One pair parr ell sides 2 right angles
A trapezium has 1 pair of opposite parallel sides of different lengths
A trapezium has only 1 pair of parallel lines.
An isosceles trapezoid must have a pair of parallel sides and a pair of congruent sides
One pair? If it is one pair of parallel sides, then it is a trapezoid. If it has 2 pairs of parallel sides, then it is a parallelogram.
I am a trapezium...
yes it does have ONE pair of parellel sides (check grammar, it should be "does *a trapazoid *have one pair of parellel sides"?
A trapezium.
paralellogram
A quadrilateral that has only one pair of parallel sides (the other pair not parallel) is a trapezium.
This quadrilateral is a trapezoid. In a trapezoid, one pair of opposite sides is parallel, and one pair of opposite sides is congruent. The other two sides are not parallel or congruent.
