A quadrilateral doesn't have degrees. It has four sides, four inside angles, four outside angles, a perimeter, and an area. If you add up the measures of all four outside angles, they add to 360 degrees. If you add up the measures of all four inside angles, they add to 360 degrees too.
(6-2)*180 = 720 degrees.
It Adds Upp Too 180..x
A trapezium is a 4 sided quadrilateral and its 4 interior angles add up to 360 degrees
The angles of a rectangle are 90+90+90+90= which make it to 360 degrees. Please add trust points too.
