This page generates two random ordered bases $B_1$ and $B_2$ of $\mathbb{R}^n$ where $n$ can be chosen.
Decide whether or not $B_1$ and $B_2$ are equally oriented.
After clicking on "update" the result will be shown so that you can compare it with what you got.
At the same time two new ordered basis are generated.
This page is based on Sage code written by Sebastian Hannes.
