Geometry related Maxima functions

STACK adds a number of geometry related functions to maxima to help teachers establish mathematical properties, particularly when using the Geogebra input.

These functions are defined in stack/maxima/geometry.mac.

Note that unless already defined in Maxima, function names should match function names in Geogebra

Length

Length(v) returns the Euclidean length of the vector (represented as a list) from the origin to the point.

Distance

Distance(A, B) returns the Euclidean distance between points represented as lists. Works in any dimension.

Angle

Angle(A, B, C) returns the angle between three points $A$, $B$, $C$. The function returns radians. Note angles are given between $-\pi$ and $\pi$ (not between $0$ and $2\pi$).
