rhombus
square and rectangles are technicality squares
An irregular quadrilateral.
Regular Shape: A Regular shape has the same amount of symmetry as how many sides it has.
I believe that there is no such shape.

pentagon
The line of symmetry in a shape is found be looking at the sides of the shape. If you see that two sides look the same, try to draw a straight line through them. The line of symmetry acts like the dotted line in which you fold you paper. If you can fold the shape across the line of symmetry, and the shape is exactly the same on both sides then you have found A line of symmetry.

a circle
octagon
I believe that there is no such shape.
It is a rhombus
An iscoceles triangle that is either obtuse or acute
Irregular shapes have NO lines of symmetry and all the sides are not the same. A regular shape WILL have lines of symmetry and all the sides are the same. * * * * * Wrong! A kite, for example, is an irregular but it has reflective symmetry. A parallelogram is an irregular quadrilateral but has rotational symmetry.
