All non rectangles are non squares.
Every non-rectangular parallelogram has. (It's not correct to say that a parallelogram has, because rectangles and squares are parallelograms too.)
True. All rectangles are trapezoids. (In England a trapezoid is known as a trapezium.)
The number line includes all rational numbers but also has irrational ones. It is the REAL number line. The square root of non-perfect squares are on it and pi is also on it and they are not rational.

Most famously, an imaginary number, that is, a number whose square (which is the number multiplied by itself) is negative. All real numbers have positive squares. A complex number, is a number which is the sum of a real number and an imaginary number, and so is also a non-real number.

Quadrilaterals are things with four sides, like squares, rectangles, diamonds, trapezoids, rhombuses. Anything that doesn't have four sides (an infinite list) is a non-example of a quadrilateral.
All positive integers which are not perfect squares.

A cube.
No. 1.5^2 = 2.25 is rational.

All sorts of figures. The only regular polygons that can tessellate by themselves are triangles, squares and hexagons. Irregular polygons such as rectangles, rhombuses, parallelograms and trapeziums will as well. Regular octagons combined with squares will. Other regular polygons can be combined with appropriate star-shapes to tesselate. There are also Penrose tilings which, although they cover the plane, are non-periodic in the sense that the pattern does not repeat itself if you move along. Finally there are many irregular shapes that will tessellate.
Not if the rectangles are non-overlapping.
A polygon is usually defined as a plane figure bounded by straight line segments. Any figure which does not correspond to this definition would be a non-polygon. For example, triangles, rectangles, squares, and even star shapes are called polygons. A circle, semicircle or oval is not a polygon. The have curved boundaries.
