Students will learn how to find the angle of rotation for points and polygons, about the origin or about a vertex of the polygon. Start with problems where the angle is a multiple of \(90^\circ,\) making sure that students can express the angle as both a clockwise and counterclockwise angle, when the angle isn't \(180^\circ.\) Next, give your students problems where the angle is not a multiple of \(90^\circ.\) For multiple choice problems students can estimate the angle. For non-multiple choice problems, students will have to measure the angle of rotation using a protractor. I think both multiple choice and non-multiple choice problems should be given. Conclude by giving your students this challenge.
