Construct a Circumscribed Quadrilateral in the Hyperbolic Disk


Using the tools in the toolbar the below, circumscribe a regular quadrilateral in the given circle. Note that not all circles can be circumscribed, so you have to be a bit careful. The quadrilateral will have four sides of the same length, and all angles are the same measure.

You should have already completed the inscribed quadrilateral problem, so that you are familiar with how to use the tools. After doing your construction, Try moving the points A and O around to get a better feeling for how the figure can vary, and how the construction will break down.

Note that it is impossible for A to be a vertex of your quadrilateral; I expect A to be the midpoint of one of the sides.

After you have successfully made the construction, enter the password you get at the bottom of the page so I can give you credit.
