i dont think it can be true that a trapizoid has 4 obtuse angles because it would not be a trapizoid , a trapiziod needs at least 2 acute angles to be wat it is that is why a trapizoid can not be all obtuse angles.
No. A trapezoid is a quadrilateral, and therefore must have an interior angle sum of 360 degrees. Any obtuse angles must be offset by acute ones, unless they’re all right angles/it’s a rectangle. 91 + 91 + 91 + 91 = 364 > 360.
