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.
A triangle can have only one obtuse angle
Yes
No, they do not.
