Learning goals: Teacher Facing Comprehend that the phrase “rigid transformation” refers to a transformation where all pairs of “corresponding distances” and “corresponding angle” measures in the figure and its image are the same. Draw and label a diagram of the image of a polygon under a rigid transformation, including calculating side lengths and angle measures. Identify (orally and in writing) a sequence of rigid transformations using a drawing of a figure and its image.
