rhombus
A rhombus or rhombis a quadrilateral whose four sides all have the same length - wikipediaA parallellogram doesn't need to have sides of the same length. Only the parallel sides have to be equally long.So the answer is noA rhombus will always be a parallellogram though.
A scalene triangle (all unequal side length's).
A shape with sides of unequal length.
scalene-unequal length sides and unequal anglesisosceles-two equal length sides(legs) and two equal anglesequilateral- three equal length sides and three equal angles
it is a trapezium
All three sides are unequal in length.
All sides unequal in length? You're not going to get this in planar geometry. You might get it in spherical, but you cannot get a flat shape to have all the same angle, yet have all unequal sides. It's not going to happen. â–
rhombus
A trapezium has two parallel sides (of unequal length) and two non-parallel sides.
No, because then it would not be a rhombus which must have 4 sides of equal lengths.
The area of a parallelogram (even with unequal adjacent sides) is still the base times the height. But the height is not the length of a side but the distance (at right angles to the base) between the base and the side parallel to it.
