Do You Know Which Line Is Euler's Line? (Geometry) T-Shirt

No need to be a mathematician or geometrician to know about Euler's line. In geometry, the Euler line, pronounced "oiler", is a line determined from any triangle that is not equilateral. This line passes through several important points determined from the triangle, including the orthocenter, the circumcenter, the centroid, and the center of the nine-point circle of the triangle.
