No.
For example, if one angle measures 100 degrees, and its adjacent angle is 80 degrees, then the opposite angles would be either 200 or 160 degrees, but in order for a quadrilateral to be inscribed in a circle the opposite angles would have to equal 180 degrees.
A parallelogram can be inscribed in a circle if it is a rectangle.
What else can I help you with?
If a parallelogram is inscribed in a circle it must be a rectangle?
Yes, a parallelogram inscribed in a circle must be a rectangle. This is because a circle's inscribed angle theorem states that the opposite angles of a cyclic quadrilateral (a quadrilateral inscribed in a circle) must be supplementary. In a parallelogram, opposite angles are equal, which can only hold true if all angles are right angles, thus making the parallelogram a rectangle.
Is it possible that a parallelogram be inscribed in a circle?
All geometric shapes can be inscribed in a circle, since the circle is bigger than the other geometric shape inscribed in it. (Obviously)
Can a rectangle always be inscribed in a circle?
Yes.
Can a rhombus always be inscribed in a circle?
yes.
Will an inscribed angle always have its vertex on the circle?
Yes all inscribed angles in a circle have their vertex on the circumference of the circle. Central angles have their vertex at the center of the circle.
What parallelogram can be inscribed in a circle?
if a parallelogram is inscribed in a circle it is always a rectangle...............
Is a parallelogram inscribed in a circle always a rectangle?
Yes. The corners must be right angles for it to be inscribed on the circle.
If a parallelogram is inscribed in a circle then it must be a?
If a parallelogram is inscribed in a circle then it must be a cyclic quadrilateral.

True or false if a parallelogram inscribed in a circle it must be a rectangle?
True.
Why is the center of a circle inscribed in a triangle always the incenter?
That is the definition of the incenter; it is the center of the inscribed circle.
Can a square always be inscribed in a circle?
yes
Can a rectangle always be inscribed in a circle?
Yes.
Can a rhombus always be inscribed in a circle?
yes.
Will an inscribed angle always have its vertex on the circle?
Yes all inscribed angles in a circle have their vertex on the circumference of the circle. Central angles have their vertex at the center of the circle.
Can an isosceles trapezoid be inscribed in a circle?
Yes, always.
