Below is an example of an ideal triangle in the Beltrami-Klein model:
Below is an example of an ideal triangle in the Poincaré disc model:
Below are some examples of ideal triangles in the upper half plane model:
speaking, none of these figures are triangles in hyperbolic geometry; however, ideal triangles are useful for proving that, given with , there is a triangle in hyperbolic geometry whose angle sum in radians is equal to .
