No a quadrilateral can't have 3 obtuse angles and 1 right angle because if a polygon did have 3 obtuse angles and 1 right angle then it would not even be a quadrilateral.
Impossible. You cannot have an obtuse angle without an acute angle in a quadrilateral.
Yes
Yes.
There can be at most 3 obtuse angles in a quadrilateral.
no,it can have a maximum of 2 obtuse angles

Yes a 4 sided quadrilateral can have angles that include obtuse angles providing the that all the 4 interior angles add up to 360 degrees.
No, a quadrilateral couldn't have four obtuse angles because the four interior angles of a four-sided quadrilateral add up to 360 degrees, and the sum of the measures of four obtuse angles would be greater than 360 degrees.
Yes
No, they do not.
A triangle can have only one obtuse angle
Yes.
