Calculate the shortest distance from the vertex of a Schweikart triangle to the opposite side

Let ∆ be an ideal triangle in the hyperbolic plane H2 with one right angle
at P and two other vertices at infinity. In other words, suppose you are given two
hyperbolic lines a and b intersecting at a right angle at P, and a third hyperbolic line c
ultraparallel to both a and b. The distance of c to P is defined as the minimum distance
of a point on c to the point P. Calculate this distance.
Can anyone give me a hint on how to tackle the problem?

  • How about drawing the setup in the Poincare model?

  • The problem is that I'm sure the shortest distance is the Euclidean distance, but i don't know how that would look on the disk.

  • Distance in the Poincare model is almost never equal to Euclidean distance. Do you know the form of the metric in any model, such as the Poincare disc model?
