360 because ALL quadrilaterals have an angle sum of 360
The sum of all (interior) angles must equal 360 degrees
All polygons with four angles (quadrilaterals) have a inner angle sum of 360 degrees.
360, since all quadrilaterals' interior angles add up to 360.
A trapezium is a quadrilateral and, as with all quadrilaterals, its interior angles sum to 360 degrees.

All polygons with four angles (quadrilaterals) have a inner angle sum of 360 degrees.
360, since all quadrilaterals' interior angles add up to 360.
The sum of the exterior angles of all polygons equals to 360⁰.Since only the sum of the interior angles of all quadrilaterals equals to 360⁰, the polygon must have 4 sides.
A trapezium is a quadrilateral and, as with all quadrilaterals, its interior angles sum to 360 degrees.
A trapezoid is a quadrilateral and like all quadrilaterals it will have a total sum of 360 degrees of interior angles.
Well a Rhombus is a quadrilateral like a square or a rectangle, and the sum of the interior angles of all quadrilaterals is 360 degrees. So the sum of the interior angles of a rhombus is 360 degrees.
Both are quadrilaterals, so the sum of their angles is 360⁰.
The sum is equal to 360 degrees.
The interior angles of all quadrilaterals sum to 360 degrees. Since a parallelogram is a quadrilateral, its interior angles must sum to 360 degrees.
(number of sides-2)*180 = sum of interior angles
