= -x + 2. Find the remaining vertices
PERSEVERE A quadrilateral in the coordinate plane has exactly two lines of symmetry, y = x-1 and y
of the figure if there is a vertex at (-1,0). Graph the figure and the lines of symmetry on a separate sheet of paper.
List the coordinates of the vertices by starting with the vertex at (-1,0) and moving clockwise around the quadrilateral.
