English: This is an image of the Neuberg cubic associated with a plane triangle ${\displaystyle ABC}$. It also shows one of the defining properties of points ${\displaystyle X}$ on the curve: If ${\displaystyle X_{A},X_{B},X_{C}}$ are the reflections of ${\displaystyle X}$ on the sidelines ${\displaystyle BC,CA,AB}$ of the triangle ${\displaystyle ABC}$, then the lines ${\displaystyle AX_{A},BX_{B},CX_{C}}$ are concurrent.
