Any regular polygon with an odd number of sides.
A trapezium does not have to have adjacent sides equal, but might have. In the US, trapezium just means any old four-sided shape. Outside the US, it means a shape with at least two parallel sides.
dimond it is the most esayest thing in the world
A Kite : This is a quadrilateral having two pairs of adjacent sides equal in length.
If it has four equal sides, then two parallel sides implies two PAIRS of parallel sides. The shape is a rhombus.
a parallelogram.

All squares have TWO SETS of opposite, parallel sides. A square is a parallelogram with 4 equal sides and 4 equal angles (right angles) of which adjacent sides are perpendicular. The related parallelogram, the rhombus, or "diamond" shape, also has 4 equal sides, but no right angles, where opposite angles are equal and adjacent angles are supplementary (sum to 180 degrees).
Parallelogram is a quadrilateral with opposite sides both parallel and equal in length - commonly known as a rectangle.

A Quadrilateral Kite!
A parallelogram is a four sided shape where opposite sides are parallel and equal lengths. If you mean that ALL sides are equal lengths, you are looking for a rhombus.
