PolySet of shapes to prove Pythagoras' Theorem:
a*a+b*b = c*c.
Usage
data(pythagoras)
Format
4 column data frame: PID = primary polygon ID,
POS = position of each vertex within a given polyline, X
= X-coordinate, and Y = Y-coordinate. Attributes:
projection = 1.
Note
In R, the data must be loaded using the data function.
Source
