When we want to create a reflection image we multiply the vertex matrix of our figure with what is called a reflection matrix The most common reflection matrices are for a reflection in the xaxis $$\begin{bmatrix} 1 & 0\\ 0 & 1 \end{bmatrix}$$ for a reflection in the yaxis $$\begin{bmatrix} 1 & 0\\ 0 & 1 \end{bmatrix}$$ for a reflection in the origin $$\begin{bmatrix} 1 & 0\\ 0 & 1 \end{bmatrix}$$ for a reflection in the lineReflection The second transformation is reflection which is similar to mirroring images Consider reflecting every point about the 45 degree line y = x Consider any point Its reflection about the line y = x is given by , ie, the transformation matrix must satisfy which implies that a = 0, b = 1, c = 1, d = 0, ie, the transformation matrix that describes reflection about the line y = x Reflection about the line #y = x# The effect of this reflection is to switch the x and y values of the reflected point The matrix is #A = ((0,1),(1,0))#
