24.15.3 Checking whether four points are concyclic in the plane
See Section 25.11.7 for checking for concyclicity in
three-dimensional geometry.
The is_concyclic
command determines whether or not points are cyclic.
-
is_concyclic takes
L, a list or sequence of points.
- is_concyclic(L) returns 1 if the points
in L all lie on the same circle, and returns 0 otherwise.
Examples
is_concyclic(1+i,-1+i,-1-i,1-i) |
is_concyclic(i,-1+i,-1-i,1-i) |
