a tetrahedon
A parallelogram does not have to be four right angles. A parallelogram is a four sided shape with two parallel lines.
A shape with parallel sides but no right angles is called a parallelogram
a parallelogram, maybe?
A trapezium (has only one pair of unequal parallel lines).
No shape does. If it has 4 sides and one pair of parallel lines it cannot have only 1 right angle, it must either have: 1) 2 right angles, 1 acute acute and 1 obtuse angle; or 2) no right angles, 2 acute angles and 2 obtuse angles; in which case it would be a trapezium (trapezoid).
A shape with no right angles and one pair of parallel lines would be called a trapezoid in the USA, and a trapezium in Britain.
Parallelogram
A Trapizoid.
The rhombus.
None
trapezoid
No because the shape would have two right angles because of the parallel lines and the limited number of angles available...just no.
hexagon
kite :)
Such a shape cannot exist.
a square and a rectangle
