Fuzzy Triangle and Fuzzy Trigonometry

Abstract

The counterpart of a crisp triangle, C, in Euclidian geometry, is a fuzzy triangle. It is helpful to visualize that a fuzzy transform of C as the result of execution of the instruction—Draw C by hand with an unprecisiated spray pen. Here the fuzzy-transformation is an one-to-many function. In this chapter, concepts about fuzzy triangle, fuzzy triangular properties and some basics of fuzzy trigonometry (Ghosh and Chakraborty 2018) are proposed. © 2019, Springer Nature Switzerland AG.
