Triangle ABC was constructed with the origin as the centroid.
Triangle is formed by expressing the coordinates of A, B, and C as z-scores.
Drag point A around so that the correlation (r) is equal to zero. Click on the CAPTURE button.
Repeat this over and over by moving point A to another spot that produces a correlation of zero and clicking on Capture.

When the correlation is zero, what happens to Triangle ? What path does A move along to produce a correlation of zero?
