== == yes. suppose the quad ABCD has AB and CD equal and parallel. Then the triangles ABC and CDA are congruent by SAS axiom; so the quad is a parallelogram
it not a straigh line
A quadrilateral is any figure with 4 sides. ("quad" = 4, "latus" = side). It doesn't have to have any parallel lines. If it happens to have two sides that are parallel, then it's a trapezoid. If it happens to have two pairs of parallel sides, then it's a parallelogram. Common parallelograms are rectangles, squares, and kites.
No, because quad means four (4) and lateral means sides. Any four-sided shape is a Quadrilateral. But the sides have to straight and a two-dimensional (2d). Some quadrilaterals have two (2) parallel sides, like a parallelogram.
Any polygon with any even number of sides CAN have 2 pairs of parallel lines. Parallelograms, rhombuses, rectangles, and squares always do.The shape that has two pairs of parallel sides is a parallelogram. It is either a rectangle, rhomboid, square, or rhombus (all special cases of the parallelogram)The set of parallelograms is is often confused with the set of trapezoids. Trapezoids are a little confusing in themselves because, although mathematicians world-wide define them as quads with two (and only two) parallel sides, in Britain trapezoid is sometimes used to refer to a quad with no parallel sides. ref. Merriam-Webster's Collegiate Dictionary.
No, in fact, no shape can be both a trapezoid and a rhombus. A rhombus is a quadrilateral with 4 equal sides. Since these 4 sides are equal, it makes the quad a parallelogram meaning BOTH sets of opposite sides are parallel. In a trapezoid, ONLY ONE pair of opposite sides are parallel.

quad

None at all, it's not possible.
All quadrilaterals have 4 sides hence the root word quad. If you have 4 equal sides with 4 equal angles you have your basic square.

4. Thus the name. Quad means 4.

a ball with four sides i guess, cause anything with quad in it had four sides

If you are smart you will know that a quad dose have a equal lengthA.S
