Pentagon
A kite or various miscellaneous quadrilaterals with no particular name.
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).
Octagon
Irregular Rhombus
what shape has 2 right angles , no lines of symmetry , 1 pair of parallel sides and no equal sides ?
a parelelogram
A Hexagon has 3 pairs of parallel line and all angles are obtuse.
Yes
a diamond does. There are two obtuse angles in it.
It is nearly the shape of a square but one side is sloping and I think it is called a trapezoid
A trapezoid!
I'm sorry there is no possible way to make a parallel lines form a right angle in any sort of shape unless u where to bend one of the lines in which case they would no longer be parallel.
