🧪 Mathematics Geometry Simulation

Interactive triangle geometry lab: drag the three vertices and watch the centroid, circumcenter, incenter and orthocenter update live, with the circumcircle, incircle and Euler line drawn in real time.

This simulator turns the classic triangle-centers construction into a hands-on lab. Drag any of the three vertices and watch the centroid, circumcenter, incenter and orthocenter recompute in real time from the live vertex positions, alongside the circumcircle, incircle and the Euler line that always threads through three of those four points. Live readouts track side lengths, interior angles, area, perimeter, and the two radii, while the Euler-line panel continuously verifies the invariant HG = 2·GO — a relationship that holds for every possible triangle shape, not just special cases.

⚙ Under the hood

This simulation demonstrates geometric concepts such as shapes, angles, and area. It provides an interactive way to learn about fundamental geometry principles.
