Dynamic Pascal Theorem

Pascal's theorem can be dynamically presented in HTML5 with Javascript.

We give a geometric solution of the next problem shown on a dynamic figure implemented in JavaScript.

Pascal Theorem. If a hexagon's vertices $P_0$, $P_1$, $P_2$, $P_3$, $P_4$ és $P_5$ are on a conic, then the points $$G=P_0P_1 \cap P_3P_4,\ \ G=P_2P_3\cap P_5P_0\ \ H=P_4P_5\cap P_1P_2$$ are collinear.

Below is the dynamic demonstartion. To move the points you should move the appropriate sliders... :-)


b = 150

x0 =
x1 =
x2 =
x3 =
x4 =
x5 =

The HTML and JavaScript code was written by my son Levente. I was just encouraging him and a bit tailored the result for this page.
