Yes, be it a common convex quadrilateral or a concave quadrilateral.
For a convex quadrilateral, the most obvious example is a irregular trapezium, where the upper base and the lower base are of different length, and the slanted sides are of different length.
It is similar for a concave quadrilateral.

A quardrilateral where each angle is a right angle?
A quadrilateral with all right angles is a rectangle.
Which quadrilateral has diagonals that always bisect its angles and also bisect each other?
Square
What shape has 2 sides that measure 25 feet each and 2 sides that measure 10 feet each?
It is an irregular quadrilateral if the 2 long sides are adjacent, and a parallelogram if the two long sides are not adjacent, because having two sets of opposite sides of equal length must form parallels. Only if all of the angles are right angles would it be a rectangle.
What are opposite angles?
Opposite angles are angles across from each other in intersecting lines. For example, see the figure below:a-> X
What is the measure of each angle of a regular triangle?
60o Angles in a triangle sum to 180o With 3 angles all the same each one is 180o ÷ 3 = 60o
