Loading Reflection around y=xDec 04, · Reflection in a Line A reflection over a line k (notation r k) is a transformation in which each point of the original figure (preimage) has an image that is the same distance from the line of reflection as the original point but is on the opposite side of the line Remember that a reflection is a flip Under a reflection, the figure does not change sizeA reflection is a flip over a line You can try reflecting some shapes about different mirror lines here How Do I Do It Myself?
For a reflection in the line y=x $$\begin{bmatrix} 0 & 1\\ 1 & 0 \end{bmatrix}$$ Example We want to create a reflection of the vector in the xaxis $$\overrightarrow{A}=\begin{bmatrix} 1 & 3\\ 2 & 2 \end{bmatrix}$$ In order to create our reflection we must multiply it with correct reflectionThose that do are said to be chiral Consider the geometry of the left figure in which a point x_1 is reflected in a mirror (blue line) Then x_r=x_0n^^(x_1x_0)·n^^, (1) so theReflections across the line y = x A reflection across the line y = x switches the x and ycoordinates of all the points in a figure such that (x, y) becomes (y, x) Triangle ABC is reflected across the line y = x to form triangle DEF Triangle ABC has vertices A (
