Figure 3a Examples of use of the functions included in the package that represent affine transformations in the plane. In all the pictures, the blue triangle, placed at the points A(0,0), B(2,0) and C(1,1), is the one passed to each of the functions, being the orange triangle the output resulting for each of the transformations. - A reflection.
