It is not a quadrilateral because quadrilaterals are figures that have four sides (thus the use of quad meaning four). A triangle only has three
There are infinitely many plane figures, not just five! A circle, ellipse, A triangle, quadrilateral, pentagon, hexagon, heptagon, octagon, and on and on. And then there are mixed figures such as a semicircle, a segment of an ellipse. Not forgetting plane figures that have "random" boundaries.
There exists at least one quadrilateral which is not 4-sided.
It means four sides, and refers to plane figures bounded by four straight sides.
Yes. "Quadrilateral" means all possible figures that have four sides. Some of them are parallelograms, some are rhombera, some are rectangles, some are squares, some are nothing in particular, and some are trapezoids.
quadrilateral
Any type of quadrilateral. This includes squares, trapeziums, parallelograms, rectangles, rhombi, etc. Hope this helped!

Quadrilateral
yes they are all four sided figures classifying them as quadrilaterals
A quadrilateral with two parallel sides is a trapezoid.
A Quadrilateral. Figures that have four equal sides are called squares. Whereas, other figures that have four unequal sides are called quadileterals

Yes, you may think of "closed figure" as part of the definition of a quadrilateral.
There exists at least one quadrilateral which is not 4-sided.
It means four sides, and refers to plane figures bounded by four straight sides.
Four-sided figures include: quadrangle, oblong, quadrilateral, parallelogram, rhombus, diamond, rectangle, lozenge, square, rhomboid, kite, trapezium, trapezoid.
