English: triangulation
Welsh: triongliant
Subject: Cyllid ac ystadegau
Welsh definition: In the social sciences, triangle is often used to indicate that two (or more) methods are used in a study in order to check the results of one and the same subject. The concept of triangulation is borrowed from navigational and land surveying techniques that determine a single point in space with the convergence of measurements taken from two other distinct points. The idea is that one can be more confident with a result if different methods lead to the same result. Triangulation is a powerful technique that facilitates validation of data through cross verification from two or more sources. In particular, it refers to the application and combination of several research methods in the study of the same phenomenon.
