You can split any rectangle up into three trapezoids but you can not combine just any three trapezoids to make a rectangle.
a rectangle a square and a trapezoid
No, a trapezoid could not have three right angles. If it did, it would be a rectangle, as the fourth angle would need to be 90 degrees as well. A rectangle is not a trapezoid.
Rectangle and Isosceles Trapezoid
A rectangle, a square, and an isosceles trapezoid.
Isosceles trapezoid and rectangle
A square is a rectangle (whose sides are all equal), or a rhombus (whose angles are all equal).
No because otherwise it would be a rectangle
A rectangle that is not a square. Or a trapezoid.
A trapezoid and a rectangle are both polygons.
No, because then it would be a rectangle.
A quadrilateral. It may be a rectangle, parallelogram, trapezoid, or an irregular quadrilateral.
by definition, there is no such a thing. It cannot be both at the same time. Three types of quadrilaterals are: Rectangle, Trapezoid, and paralelogram; that is it.
