It is just an irregular quadrilateral.
isolese triangle
noA 4th angle would have to be obtuse, because the acute angles could not sustain a quadrilateral.
it is an irregular shape
A trapezoid contains either:two acute angles and two obtuse angles orone acute angle, one obtuse angle and two right angles.
Impossible. You cannot have an obtuse angle without an acute angle in a quadrilateral.

A trapezoid can have 2 right angles, an obtuse and an acute angle Or a kite.

No, an obtuse triangles has one obtuse angle and two acute angles. If a triangle has an obtuse angle, it is considered obtuse and cannot be acute.
They will be acute angles.
For any quadrilateral (i.e. 4-sided figure), the angles will add up to 360 degrees. Since an obtuse angle is any angle with a measurement over 90 degrees, it is possible to have a quadrilateral with 3 obtuse angles. The fourth angle, however, must be acute (i.e. smaller than 90 degrees). Having 3 obtuse angles is not a requirement, however, for a quadrilateral.
A trapezoid contains either:two acute angles and two obtuse angles orone acute angle, one obtuse angle and two right angles.
Not possible... The internal angles of a quadrilateral always total 360. If you MUST have an angle of 90 degrees - the remaining angles must total 270. At least one of the remaining angles will always be obtuse.
