When we talk about "dissecting" a parallelogram and rearranging the parts to form a rectangle in order to determine the area of the parallelogram, we are clearly referring to the edges and the interior. How to Find the Circumradius of a Triangle. Students Love Study. However, the proof must wait until we develop a counting formula called the Euler characteristic, which will arise in our chapter on Non-Euclidean Geometry. A quadrilateral is a polygon composed of four sides and four angles. A rhombus with congruent sides could have sides that all measure four inches in length. A quadrilateral is a four sided polygon that can be classified in several categories based on its properties.
