1. Introduction
The construction of an interesting geometric figure is best carried out after an
analysis. For example, given a triangle ABC, how does one construct a point P
through which the parallels to the three sides make equal intercepts? A very simple
analysis of this question can be found in [6, 7]. It is shown that there is only one
such point P, 1 which has homogeneous barycentric coordinates

This leads to a very easy construction of the point 2 and its three equal parallel
intercepts. See Figure 1. An interesting variation is to consider equal “semi-parallel
