Rigid Transformations in Geometry

The video introduces rigid transformations, focusing on reflection, translation, and rotation. It explains that rigid transformations do not alter the size or shape of figures. Reflection involves flipping a shape over a line, translation is moving a shape without rotation, and rotation involves turning a shape around a center point. Key questions for each transformation type are discussed, and the video concludes with a review.
