Yes, a rectangle can be a parallelogram. A rectangle is a type of parallelogram with all angles equal to 90 degrees. Additionally, opposite sides of a rectangle are equal in length. Therefore, all rectangles meet the definition of a parallelogram, but not all parallelograms are rectangles.
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.
If a parallelogram is inscribed in a circle, it must be a rectangle. This is because the opposite angles of a parallelogram are equal, and for it to fit inside a circle, all angles must be right angles, ensuring that the opposite sides are equal and parallel. Therefore, the only type of parallelogram that can be inscribed in a circle is a rectangle.

If a parallelogram is inscribed in a circle then it must be a cyclic quadrilateral.

It is 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.
No, since all rectangles must be parallelograms.
A rectangle, possibly a square. Can you see why a parallelogram must be a rectangle if any one of its angles is right?
Adjacent sides of a parallelogram nee not meet at right angles. In a rectangle they must.
