Urawa Red Diamonds and fixtures between them were known as "Marunouchi derbies", although the term is falling out of use as they are now based in different prefectures and rarely play home games in Tokyo stadiums.

Incircle and excircles of a triangle is also known as the extouch triangle of "ABC". The circumcircle of the extouch triangle "TTT" is called the Mandart circle. The three lines "AT", "BT" and "CT" are called the splitters of the triangle; they each bisect the perimeter of the triangle, The splitters intersect in a single point, the triangle's Nagel point "Na" - "X(8)". Trilinear coordinates for the vertices of the extouch triangle are given by Trilinear coordinates for the Nagel point are given by or, equivalently, by the Law of Sines, It is the isotomic conjugate of the Gergonne point. In geometry, the nine-point circle is
