Sal solves the following problem: Two of the points that define a certain quadrilateral are (-4,-2) and (0,5). The quadrilateral has aï¿½ï¿½ï¿½ï¿½ï¿½ï¿½ï¿½ï¿½ï¿½ï¿½ï¿½ï¿½reflective symmetry over the lines y=x/2 andï¿½ï¿½ï¿½ï¿½ï¿½ï¿½ï¿½ï¿½ï¿½ï¿½ï¿½ï¿½y=-2x + 5.ï¿½ï¿½ï¿½ï¿½ï¿½ï¿½ï¿½ï¿½ï¿½ï¿½ï¿½ï¿½Draw and classify the quadrilateral.  # Symmetry of two-dimensional shapes
