*ABCD*on graph paper. What shape is*ABCD*? Justify your answer.*ABCD*is rotated 180° about the origin to create*A*′*B*′*C*′*D*′. Then*A*′*B*′*C*′*D*′ is reflected across the*x*‑axis to form*A*″*B*″*C*″*D*″. Name the coordinates of*C*′*D*″.

Recall the properties of quadrilaterals. Do any apply to this shape?
