Vertex Model of Triangle
Let's use column vectors to create a vertex model of a triangle in two dimensions. We define our three vertices as follows:
Remark. In this model, we assume each vector represents a point in a two-dimensional space. The entry in the first row of each vertex vector encodes distance along the horizontal axis. The entry in the second row encodes distance along the vertical axis.
Remark. When we graph these vertices, we do not connect the dots because this model does not encode links between vertices.
