This math topic practices the skill of rotating points on a Cartesian grid. The problems involve rotating given points around specified axes on the grid, either clockwise or counter-clockwise, by angles such as 90 degrees or 180 degrees. The scenarios vary by altering not just the angles and directions of rotation, but also the points of rotation, which includes around origin or other specified points on the grid. Each problem provides multiple choice answers, asking to pick the correct new coordinates of the rotated point. This topic is a part of an introductory unit on Cartesian Grid Transformations.
