No, most quadrilaterals are not.
It depends on the quadrilateral. The max number is 4, but the min is 0.
an non symmetrical 4 sided shape such as a Rhombus or a Trapezoid
A shape with four non-parallel sides is an irregular quadrilateral. If the quadrilateral is bilaterally symmetrical, it is a deltoid (kite shape).
The shape with angles of 80, 100, 100, and 80 degrees in that order is a quadrilateral. Specifically, it can be classified as a kite, as it has two pairs of equal angles and symmetrical properties. The sum of the interior angles of a quadrilateral is 360 degrees, which matches the given angles.
No. Socks are not symmetrical.

In short, yes. A parallelogram is a quadrilateral with opposite sides parallel (and therefore opposite angles equal). A quadrilateral with equal sides is called a rhombus, and a parallelogram whose angles are all right angles is called a rectangle. And, since a square is a degenerate case of a rectangle, both squares and rectangles are special types of parallelograms.
No. Socks are not symmetrical.
is a arrow symmetrical
If it is a quadrilateral it cannot be "not a quadrilateral"!
Yes, it is symmetrical
No but an isosceles trapezoid is symmetrical.
No the white house is not symmetrical
Pentagons can be symmetrical, but are not always so.
