An obtuse triangle.
The most notable is a triangle, but every polygon can have an obtuse angle. An obtuse angle is anything measuring greater than 90 degrees.
A regular polygon of n sides (where n > 4) has n obtuse angles. Since there is no limit to the number of sides that a polygon can have, there can be no limit to the number of obtuse angles in a shape.
It can be an obtuse triangle.
Not sure what the question means. A triangle or quadrilateral may but need not contain an obtuse angle. A pentagon or any polygon with more sides must contain at least one obtuse angle.
Neither. A triangle is a polygon, not an angle - acute (acut, even) or obtuse.

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.
An obtuse angle is an angle that is greater than 90 degrees but less than 180 degrees. The internal angles of any regular polygon with 5 or more sides will be obtuse.

Yes. Any polygon with more than four sides MUST have at least one obtuse angle.
