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
parallelogram with one diagonal
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.

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.
A quadrilateral with 3 acute angles and 1 obtuse angle is known as a scalene trapezoid. In this type of quadrilateral, three of the angles are less than 90 degrees (acute angles), while one angle is greater than 90 degrees (obtuse angle). The sides of a scalene trapezoid are of different lengths, and the opposite sides are not parallel. This distinguishes it from other types of quadrilaterals such as rectangles or parallelograms.
acute, right, or obtuse angle
