It is a trapezoid or a trapezium
A quadrilateral
All quadrilaterals have 4 sides of various lengths and the 4 sides added together is the perimeter
The name for a quadrilateral with 4 sides of all different lengths is simply "quadrilateral". All of the specializations of quadrilaterals: parallelogram, trapezoid, kite, rhombus, rectangle, and square, have at least one pair sides with the same length.
There is no special name. And some quadrilaterals with special characteristics (eg a trapezium) could still have all sides of different lengths.
A square has all 4 sides equal in length. A four sided closed figure with all sides different length is called a quadrilateral.
No, a scalene triangle is not a quadrilateral. A scalene triangle is a type of triangle where all three sides have different lengths and all three angles are different. In contrast, a quadrilateral is a polygon with four sides and four angles. Thus, they are distinct geometric shapes with different properties.
No because a rhombus is a 4 sided quadrilateral
The only classification I could give this figure would be that it is a trapezoid, perhaps.
A trapezoid is a 4 sided quadrilateral with 1 pair of opposite parallel sides of different lengths
No, because a quadrilateral can be many different sizes and lengths as a quadrilateral is any shape with only 4 sides. The sum of all the angles in a quadrilateral equal 360 degrees.
Yes, a quadrilateral can have no parallel lines. For example, a general irregular quadrilateral, where no sides are equal or parallel, fits this description. Such a shape can have all four sides of different lengths and angles, resulting in no parallel sides.
No. Take a pencil and a sheet of paper. You shouldn't have any trouble drawing something with 4 sides that are all different lengths.
