The circumcenter of a polygon is the center of a circle circumscribed about a polygon. The incenter of a polygon is the center of a circle inscribed in the polygon. If a quadrilateral is inscribed in a circle, its opposite angles are supplementary. If a parallelogram is inscribed in a circle, it must be a rectangle.
Which polygons can have circumscribed circles?
Not every polygon has a circumscribed circle. A polygon that does have one is called a cyclic polygon, or sometimes a concyclic polygon because its vertices are concyclic. All triangles, all regular simple polygons, all rectangles, all isosceles trapezoids, and all right kites are cyclic.
What is the difference between an inscribed polygon and a circumscribed polygon?
In summary, an inscribed figure is a shape drawn inside another shape. A circumscribed figure is a shape drawn outside another shape. For a polygon to be inscribed inside a circle, all of its corners, also known as vertices, must touch the circle.

Can a polygon be circumscribed?
In Euclidean geometry, a tangential polygon, also known as a circumscribed polygon, is a convex polygon that contains an inscribed circle (also called an incircle). This is a circle that is tangent to each of the polygon’s sides.
What is a circumscribed angle?
A circumscribed angle is the angle made by two intersecting tangent lines to a circle. Now we can draw two radii from the center of the circle to points A and B on the edge of the circle. The sum of all of the angles in a quadrilateral is 360°.
What is circumscribed math?
Circumscribed Meaning. The meaning of circumscribed in Geometry is drawing a figure around another figure in such a way that the drawn figure touches the outer line or points of the inside figure without intersecting it.
What Quadrilaterals can be circumscribed?
A cyclic quadrilateral is a quadrilateral for which a circle can be circumscribed so that it touches each polygon vertex. A quadrilateral that can be both inscribed and circumscribed on some pair of circles is known as a bicentric quadrilateral.
