What is the only way to circumscribe a circle around a parallelogram?

The only way to circumscribe a circle around a parallelogram is when the parallelogram is a rectangle. This is because only rectangles have all four angles equal to 90 degrees, which allows a circle to be inscribed such that all vertices are equidistant from the center. In general, a circle can be circumscribed around a polygon only if the polygon is cyclic, and rectangles are the only type of parallelogram that meet this criterion.


How could you contrust a rhombus circumscribed in a circle?

You cannot circumscribe a "true rhombus". The opposite angles of a circumscribed quadrilateral must be supplementary whereas the opposite angles of a rhombus must be equal. That means a circumscribed rhombus is really a square.

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.


If a circle is circumscribed around a triangle then how many of the triangle's vertices must it pass through?

What is a circumscribed polygon?
