I believe that there is no such shape.
An isosceles trapezoid.
Hexagon
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.
A rectangle.
Rectangle
An irregular quadrilateral.
no shape does! * * * * * Not true. A parallelogram has rotational symmetry of order 2, but no lines of symmetry.
Try one of these: rhombus, parallelogram, square, rectangle
A rectangle has exactly 2 lines of symmetry
a square
I think the shape is a star
