Triangle is the closed basic shape in the geometry which has three edges and three vertices. There are three types of the triangle which are classified on the basis of the length of their sides and it is also classified on the basis of the internal degree of the triangles. It is a two-dimensional figure. So take this quiz and know more about the triangles.
