Representation of similar triangles in $\mathbb{R}^{3}$

Abstract

In 1994, Dhar and Sinha provided a graphic representation in $\mathbb{R}^{2}$ of the classification of triangles based on similarity. In this article, we briefly recall their treatment and offer a generalization by providing a graphic representation in $\mathbb{R}^{3}$. Towards the end of this article, we make an attempt to offer a quantitative analysis of some particular class of triangles.
