a trapezium ,perhaps
It is just an irregular quadrilateral.
octegon
Yes, a quadrilateral just need to have 4 sides. Quad- means 4 and -lateral means sides. To have only one tight angle, it has to be either a right angle with 2 acute angles and 1 obtuse angle OR a right angle with 2 obtuse angle s and 1 acute angle.
It is a right angled trapezoid
isolese triangle
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.

isolese triangle
parallelogram with one diagonal
It ha one right angle, two obtuse angles and one acute angle
It is 1 degree after a right angle. A right angle is 90 degrees so the smallest obtuse angle is 91 degrees.
acute, right, or obtuse angle
No.
How about a kite which is a 4 sided quadrilateral that can have 2 equal opposite obtuse angles
