Perpendicular Trisectors and Base Trisectors in Triangles and Quadrilaterals

Perspectives on Higher Education
The four centers of a triangle- namely centroid, circumcenter, orthocenter, and incenter are well known. These are characterized by some famous lines known as median, perpendicular bisector, altitude, and angle bisector.

What is the shape of a triangle

, 1993
We consider the problem of describing the shape of a triangle by a single complex number , which we call the shape invariant of the triangle.After giving a simple algebraic definition of , we prove a surprising geometric description: modulo a symmetry ...

From the triangle Sagnac experiment to a practical, crucial experiment of the constancy of the speed of light using atomic clocks on moving objects

, 1998
According to the triangle Sagnac experiment, between point A and point B that are moving in a circular motion, the travel times for light or radio signals from A to B and from B to A are different. The difference Δt, i.e.
