No, only in certain, limited circumstances. Eg where a quadrilateral is (can be) circumscribed within a circle.

Is it true that Opposite angles of a trapezoid are supplementary?
Wouldn't think so, think of a trapezium shaped like a square with a triangle on one side... The angles at one end of the figure are both 90o, and the angles at the other end will be supplementary, but not opposite angles.
Are the opposite angles of kite are supplementary?
no * * * * * But they can be.
Do opposite angles in a parallelogram add up to 180?
No. Opposite angles are equal. Adjacent angles are supplementary.
Is an isosceles trapezoid opposite angles supplementary?
Yes.
Supplementary angles form a linear pair?
Not necessarily. A linear pair of angles must be supplementary but supplementary angles need not form a linear pair. For example, the opposite angles of a cyclic quadrilateral are supplementary but they are (by definition) not next to one another.
True or false If opposite angles of a quadrilateral are supplementary then the quadrilateral is a parallelogram?
True
Does a rhombus have opposite angles that are supplementary?
No. The adjacent angles are supplementary.
Which property is always true for a quadrilateral inscribed in a circle?
opposite angles are supplementary
Is this statement true or falseIf a quadrilateral is a parallelogram, then its opposite angles are always supplementary?
false
True or False- If opposite angles of a quadrilateral are supplementary then the quadrilateral is a parallelogram?
false
Are opposite angles in a parallelogram supplementary?
No, they are equal. Adjacent angles are supplementary in a prallelogram.
Is it true that Opposite angles of a trapezoid are supplementary?
Wouldn't think so, think of a trapezium shaped like a square with a triangle on one side... The angles at one end of the figure are both 90o, and the angles at the other end will be supplementary, but not opposite angles.
Supplementary trapezoid opposite angles?
No, they are generally not supplementary.
Are the adjacent angles of a rhombus supplementary?
Yes, adjacent angles are supplementary; however, opposite angles are not.
Are the opposite angles of kite are supplementary?
no * * * * * But they can be.
If a parallelogram has one right angle then all of its angles must be right?
Yes. This is true because opposite angles are congruent and adjacent angles are supplementary.
Do opposite angles in a parallelogram add up to 180?
No. Opposite angles are equal. Adjacent angles are supplementary.
