Question

What quadrilateral has no congruent sides?

Answer 1

Hint: As we know that a quadrilateral is simply a two dimensional figure which has for sides. The term quadrilateral is derived from two words quad$ = $ four and lateral $ = $side. There are many types of quadrilateral such as trapezium, parallelogram, rectangle, square, rhombus and so on.

Complete step-by-step answer:
There are many quadrilaterals that have no congruent sides. One of them is Scalene quadrilateral.
We know that a scalene quadrilateral is a four sided polygon that has no congruent sides. This quadrilateral does not have any special properties. The angles and sides have different lengths and measures.
We can see the example of scalene triangle below:

Here ABCD is a scalene quadrilateral with no congruent sides.

Note: We should note that there is one rule for quadrilateral and it is true for all types of quadrilateral. The sum of all measures of exterior angles in quadrilateral is always equal to ${360^ \circ }$.
We should know that a quadrilateral is a polygon with four sides.
