Definition of a quadrilateral that is not a parallelogram and could have exactly two opposite right angles?
A rectangle is a parallelogram, and neither a trapezoid nor an isosceles trapezoid could have exactly two opposite right angles.So, a quadrilateral that is not a parallelogram and could have exactly two opposite right angles must be a kite.
What is a quadrilateral that has neither a line of symmetry nor rotational symmetry?
parallelogram
Which quadrilaterals do not have four sides of equal length?
Any quadrilateral qualifies as long as it is neither an equilateral trapezoid nor a rhombus. (That includes not a square.)
Is a parallelograms a trapezoids?
No. The formal definitions of parallelogram and trapezoid specifically exclude each other.A parallelogram is a quadrilateral with two pairs of parallel sides.A trapezoid is a quadrilateral with exactly one pair of parallel sides.
Is a quadrilateral also a parallelogram?
It may be. A quadrilateral has four sides, but they need not be all the same length, nor parallel to each other. It's true that a parallelogram *is* a quadrilateral.

Which figure is neither a trapezoid nor a parallelogram?
A circle.
Is a octagon a quadrilateral and a parallelogram?
An octagon is neither a quadrilateral nor a parallelogram. "Quadrilateral" refers to a shape that has four sides. "Parallelogram" refers to a shape that has two pairs of opposite, congruent sides. An octagon has eight sides, and since eight is not equal to four, an octagon is neither a quadrilateral nor a parallelogram.
What is a quadrilateral that has neither a line of symmetry nor rotational symmetry?
parallelogram
Opposite sides not parallelangles not equal?
A quadrilateral that is not a parallelogram, not a trapezoid nor a rhombus. It is not a square nor a rectangle. There ought to be a name for this! /Brian W

Is a rhombus a concave?
A rhombus is an equilateral parallelogram. As such, it is neither concave nor convex.
Is it true that some quadrilaterals are neither trapezoids nor parallelogram?
Yes.
Is a rhombus concave or convex?
A rhombus is an equilateral parallelogram. As such, it is neither concave nor convex.
What thirteen letter shape has 2 pairs of parallel sides 4 right angles but sides are not all the same length?
The geometric answer is a rectangle but that does not have 13 letters. The answer is NOT a quadrilateral nor parallelogram because neither of them need have 4 right angles.
