Abstract
In this note we shall prove a geometric Ramsey theorem. Let T be a tri angle with angles 30, 60 and 90 degrees, and with hypotenus of unit le ngth. Then the theorem says that if one three-colors the 3-space, then there is always a copy of T with monochromatic vertices. We shall als o show that there is a 12-coloration of the space in which there is no copy of T with monochromatic vertices.
