quadrilaterals
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.
(number of sides-2)*180 = sum of interior angles
no
quadrilaterals
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
