Quadrilateral
A trapezoid is a 4 sided quadrilateral with 1 pair of opposite parallel sides of different lengths. Its perimeter is the sum of its 4 sides. Its area is: 0.5*(sum of parallel sides)*height
You can construct any polygon with more than 4 sides such that two sides are parallel. A quadrilateral in which two lines are parallel is called a trapezoid.
Presuming our geometry is Euclidean, such a shape would be a rectangle, since all 4 angles would be right angles. If our geometry is hyperbolic, it would be possible to construct such a quadrilateral which is not a rectangle (and in fact, rectangles cannot exist in a hyperbolic geometry). I do not believe such a quadrilateral has any special name.
It is an inscribed quadrilateral or cyclic quadrilateral.
Yes.
No, equilateral and regular are the same thing.

If it is a quadrilateral it cannot be "not a quadrilateral"!

quadrilateral
A series of transformations on quadrilateral S resulted in quadrilateral T. The angles of quadrilateral S and T are congruent but the sides of quadrilateral T are twice as long as quadrilateral S. Which transformation on quadrilateral S must be included to result in quadrilateral T * sorry thats the full question!
A quadrilateral is a polygon with four sides. A rectangle is a quadrilateral
It is an inscribed quadrilateral or cyclic quadrilateral.
