Geometry and Measurement: Rotation

The video tutorial explains how to rotate a quadrilateral ABCD around the origin by -180°. It details the transformation of each point: A, B, C, and D, into their new positions by converting their coordinates to negative values. The tutorial then guides on connecting these points to form the new quadrilateral. Finally, it generalizes the process for rotating any shape on the Cartesian plane, regardless of the number of sides or rotation angle.
