Task# Lines of symmetry for quadrilaterals

Illustrative MathematicsVaries

This task provides students a chance to experiment with reflections of the plane and their impact on specific types of quadrilaterals. It is both interesting and important that these types of quadrilaterals can be distinguished by their lines of symmetry. The only pictures missing here, from this point of view, are those of a rhombus and a general quadrilateral which does not fit into any of the special categories considered here. This task is best suited for instruction although it could be adapted for assessment.
