* both pairs of opposite sides are parallel * both pairs of opposite sides are congruent * both pairs of opposite angles are congruent * one pair of opposite sides are parallel and congruent * both diagonals bisect each other * all consecutive angle pairs are supplementary
a quadrilateral has 4 sides.
No, it is not. A quadrilateral is a 4-sided polygon. A triangle is a 3-sided polygon. Therefore, whatever way you turn it, a triangle will never be a quadrilateral.
If its 4 sides are of different lengths then it will have no congruent angles
The term is quadrilateral.

The best way to describe the parallepiped is that it is a 3-d parallegram.
a quadrilateral has 4 sides.
A quadrilateral is a 4 sided shape.
No, but there is a way to prove that zero equals one.
If it has at least one set of parallel sides, then at least one set of angles are congruent
It cannot. There is no way to draw a quadrilateral where 3 sides are congruent.
A square can be distorted into a rhombus by moving one of the lines sideways (and down). In the same way, any quadrilateral can be "distorted" into another shape.
NO! You have |_\ with the other three angles adding to 270 in any way!
