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.
An isosceles trapezoid must have a pair of parallel sides and a pair of congruent sides
A quadrilateral that has only one pair of parallel sides (the other pair not parallel) is a trapezium.
A parallogram has two pairs of parallel sides. A trapezoid has one pair of parallel sides. A regular octagon has four pairs of parallel sides. An irregular octagon may have from 3 pair to no pair of parallel sides.
A trapezium.
diamond trapezium
A diamond has 2 sets of parallel sides.
No. A trapezoid only has one pair of parallel sides.
RHOMBOID
A quadrilateral has four sides that may or may not be equal or parallel If two sides are parallel and the other sides equal but not parallel it is a trapezoid
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.
