A kite or various miscellaneous quadrilaterals with no particular name.
Octagon
Irregular Rhombus
a parelelogram
A Hexagon has 3 pairs of parallel line and all angles are obtuse.
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).
Yes
a diamond does. There are two obtuse angles in it.
A trapezoid!
It is nearly the shape of a square but one side is sloping and I think it is called a trapezoid
A right angle triangle.
if you are talking about regular polygons, then nothing has an obtuse angle. otherwise, pretty much any shape can have an obtuse angle
