Always 360 degrees
quadrilaterals
Not all irregular quadrilaterals share the same properties; however, they all have four sides and angles that are not equal or do not have equal lengths. Irregular quadrilaterals can have varying side lengths and angles, distinguishing them from regular quadrilaterals like squares or rectangles. Examples include trapezoids and general quadrilaterals that do not conform to specific classifications.
Not always because its possible to have a trapezoid with 2 right angles and an obtuse angle plus an acute angle and the 4 interior angles must add up to 360 degrees
A kite or some irregular quadrilaterals.
360, since all quadrilaterals' interior angles add up to 360.

ALL quadrilaterals have 4 angles
A parallelogram, a rhombus, kites, arrowheads, trapezium and irregular quadrilaterals. However, some kites, arrowheads, trapezium and irregular quadrilaterals can have one (or more) right angles.
Not always because its possible to have a trapezoid with 2 right angles and an obtuse angle plus an acute angle and the 4 interior angles must add up to 360 degrees
A kite or some irregular quadrilaterals.
360, since all quadrilaterals' interior angles add up to 360.
Not always but all 4 sided quadrilaterals have 4 interior angles that add up to 360 degrees
A concave quadrilateral
(number of sides-2)*180 = sum of interior angles
All 4 sided quadrilaterals have 4 interior angles that add up to 360 degrees
