Abstract
In this paper we consider the line through the feet of the perpendi-
culars to the sides of a triangle from a point of its circumcircle. This
line is known as the Wallace-Simson line. The interesting elements of
history of its discovery are given. Some interesting properties of this
line are also discussed as well as the relationships with the Euler circle
of a triangle.
Keywords
