The Nagel line of ABC is the line passing through the centroid, the incenter, the Spieker center and the Nagel point of ABC. The trilinear equation of the Nagel line is + + = This is the central line associated with the triangle center X 649.
Center Line is a city in Macomb County in the U.S. state of Michigan. An inner-ring suburb of Metro Detroit , Center Line is located roughly 11 miles (17.7 km) north of downtown Detroit , and is completely surrounded by the larger city of Warren .
Interrupted center lines mean overtaking is allowed, a solid line means overtaking is not allowed, depending on which side of a double line is solid. Smaller roads and roads where bicycles are allowed generally do not have center lines, and many country roads have no lines at all. Sometimes there is a center line only in sharp curves.
The centroid of a solid hemisphere (i.e. half of a solid ball) divides the line segment connecting the sphere's center to the hemisphere's pole in the ratio : (i.e. it lies of the way from the center to the pole). The centroid of a hollow hemisphere (i.e. half of a hollow sphere) divides the line segment connecting the sphere's center to the ...
In geometry, the Euler line, named after Leonhard Euler (/ ˈ ɔɪ l ər / OY-lər), 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.
Center line, a road surface marking; Center line, a taxiway marking; Center line, a runway marking; CenterLine (OCTA), failed light-rail project in Orange County, California, U.S. Centerline (nautical), the dividing line between port and starboard sides of a ship or boat; Centreline, a bus service in Manchester, England, later rebranded ...
A central venous catheter (CVC), also known as a central line (c-line), central venous line, or central venous access catheter, is a catheter placed into a large vein. It is a form of venous access. Placement of larger catheters in more centrally located veins is often needed in critically ill patients, or in those requiring prolonged ...
A symmetry of the projective plane with a given conic relates every point or pole to a line called its polar. The concept of centre in projective geometry uses this relation. The following assertions are from G. B. Halsted. [3] The harmonic conjugate of a point at infinity with respect to the end points of a finite sect is the 'centre' of that ...
