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.

What transformation occurs to a point (X, Y) when it is rotated by 180° about the origin?

What are the new coordinates of point A after a 180° rotation?

Describe the transformation of point B during the rotation process.

What happens to the coordinates of the point (0, 0) when it is rotated?

How do you construct the quadrilateral ABCD after obtaining the four transformed points?
