The One-Seventh Area Triangle

Main Concept

The one-seventh area triangle is a special figure that can be constructed within any given triangle, using the following steps:

1. 

Draw three cevian lines, each connecting one vertex of the triangle to a point which is one-third of the distance between the vertices of the opposite side.

2. 

Let the intersections of these three cevian lines form the vertices of a smaller triangle completely contained within the original figure. This inner triangle has an area equal to one-seventh the area of the given triangle.
