rotate a square and it's still looks the same
rotate a trap and you can tell it's on its side
A trapezoid
A square.
Yes
Yes a rectangle is a special case of the parallelogram (one where any and all angles are 90°). Parallelograms are sometimes rectangles, but not always.The parallelogram is itself a special case of the trapezoid where at least one pair of opposite sides is parallel.the trapezoid is a special case of the quadrilateral, a planar convex figure with four sides.
By itself it is just a number and not a geometrical figure
A trapezoid
A square.
A trapezoid (or trapezium, outside of North America) is a four-sided figure with two opposite sides that are parallel. Thus a trapezoid is a special type of quadrilateral, which is any four-sided figure. A quadrilateral is itself a special type of polygon, which is any figure with straight sides.

The degree to which a population is replacing itself.
Itself
If it is a closed figure which doesn't cross over itself (like a bowtie looking figure), then it is called a polygon.
