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.
The shape that has two pairs of equal sides and two lines of symmetry is a rectangle. In a rectangle, opposite sides are equal in length, and it has two lines of symmetry: one vertical and one horizontal. This symmetrical property allows it to be divided into mirror-image halves along these lines.
Rectangle
An irregular quadrilateral.
no shape does! * * * * * Not true. A parallelogram has rotational symmetry of order 2, but no lines of symmetry.
A rectangle has exactly 2 lines of symmetry
a square
Yes, it is possible for an octagon to have 2 lines of symmetry, but it would not be a regular octagon. A regular octagon has 8 lines of symmetry. However, an irregular octagon can be designed with only 2 lines of symmetry if it is asymmetric in a specific way, such as having two opposite sides that mirror each other while the other sides differ in shape or length.
