360 degrees
180 degrees and for quadrilaterals there are 360 degrees. :)
All quadrilaterals have 4 interior angles that add up to 360 degrees.
360
A trapezium is a quadrilateral and, as with all quadrilaterals, its interior angles sum to 360 degrees.
All quadrilaterals (including parallelograms) have 360 degrees.
Any number from 2 to 10, depending on their relative shapes, sizes and positions.
The answer depends on the number of sides in the polygon.
No, a quadrilateral isn't always a trapezoid. One way to consider it is that all trapezoids are quadrilaterals (four-sided shapes), but not all quadrilaterals are trapezoids. Some quadrilaterals are concave quadrilaterals, some are scalene convex quadrilaterals (called trapezoids in the UK), some would be trapezoids, and some would be parallelograms (rectangles, squares, rhomboids, rhombi). If parallelograms are considered a special case of trapezoids, then trapezoids would include all non-scalene convex quadrilaterals, which is a highly inclusive definition.

All polygons with four angles (quadrilaterals) have a inner angle sum of 360 degrees.
