# Side-Splitting Triangle Ratios

Requires a Wolfram Notebook System

Interact on desktop, mobile and cloud with the free Wolfram Player or other Wolfram Language products.

Going clockwise around a triangle, place a point on each side at position of the side's length. If segments are drawn from those points to the opposite vertex, the resulting inner triangle has area with ratio when compared to the area of the original triangle. For example, when each side is divided by thirds, the inner triangle is exactly one-seventh the area of the outer triangle.

Implementation detail: each point is rounded to the nearest thousandth, so that areas can be calculated exactly.
