+ The Fréchet distance is a measure of similarity: it is the greatest
distance

distance is an
+ approximation of this metric: only vertices are considered. The
parameter

Review Comment:
This text is copied verbatim from geopandas' own docstring for
`frechet_distance`. Keeping it consistent with upstream.
