tkz-elements — update 4.42c (2025/11/24)
This update brings a new geometric class, several new Apollonius-related tools,
improved robustness thanks to extended EPS handling, and many documentation
enhancements.
Added
New class angle:
A dedicated object for angle management (identifier "A" used internally).
Integration with other classes will come in later releases.
class circle:
New method CCL (circle–circle–line tangency).
Unified similitude method with optional "internal" / "external" mode.
module tkz:
New angle-related functions, all with optional EPS:
tkz.inner_angle, tkz.angle_between_vectors, tkz.get_angle_normalize.
New comparison helper: tkz.approx (optional EPS).
class line:
Aliases perpendicular_bisector and bisector for mediator.
New method harmonic with mode "internal", "external" or "both".
class triangle:
isodynamic_points (alias neuberg_points).
three_apollonius_circles.
apollonius_circle.
apollonius_points.
apollonius_circles.
Changed
class matrice:
Fixes for print_matrix and matrix:print.
Correction of method htm.
Intersection
Complete rewrite of algorithms with a unified EPS parameter for precision
control.
class circle:
Many methods now accept an optional EPS argument:
on_circle, in_out, in_disk, in_out_disk,
in_disk_strict, out_disk_strict, in_out_disk_strict,
line_position, pole, is_tangent, is_secant,
circles_position, orthogonal_through, midcircle, common_tangent.
Improved behaviour of CLL for parallel lines.
class line
Improved LLL.
Documentation:
Some corrections
New Gothic example for CLP.
New CLL example with parallel lines.
Rewrite of search_circle.lua.
Expanded Apollonius section with new CLP examples.
Lua lesson: using string.char(37).
