Euler line
In geometry, the Euler line, named after Leonhard Euler (), is a line determined from any triangle that is not equilateral. It is a central line of the triangle, and it
passes through several important points determined from the triangle, including the orthocenter, the circumcenter, the centroid, the Exeter point and the center of the nine-point circle of the triangle.
The concept of a triangle's Euler line extends to the Euler line of other shapes, such as the quadrilateral and
approved, and the project was executed by the Seção Técnica da Linha (Technical Section of the Line), under the leadership of the engineer Carlos Euler, helped by his colleague Mário Martins Costa. The line elevation works, which included the construction of a metallic viaduct over the canal, near Leopoldina Station, started in 1905, with José de Andrade Pinto being the chief line engineer. With the elevation of the line, São Diogo lost its importance, and Lauro Muller Station opened. It was named after the transport minister
