It is possible in neutral geometry for a Lambert quadrilater

It is possible in neutral geometry for a Lambert quadrilateral to have an obtude k. The larger a triangle in hyperbolic geometry, the small, angler sum. 1. In neutral geometry, there may be two lines parallel to a given point, but if there are more, the geometry must be In hyperbolic geometry, opposite angles of a parallel. It is possible to prove the parallel postulate in neutral geometry.

Solution

t) true
