Transformations- Reflections and Symmetry

Use the sliders to change each line of symmetry in which the pre-image is reflected. Can you change the lines of symmetry so that the image maps to the pre-image? How many lines of symmetry does this quadrilateral have? Do all quadrilaterals have the same lines of symmetry? Change the points of ABCD to investigate.
