Lesson: Congruence of Polygons through Transformations Mathematics • 8th Grade

Students will be able to

• understand that the image of a plane figure under a translation, reflection, rotation, or dilation is similar to the figure,
• understand that the image of a plane figure under a translation, reflection, or rotation is congruent to the figure,
• understand that the image of a plane figure under a dilation is not necessarily congruent to the figure,
• judge whether two shapes are congruent by checking to see if one is the image of a transformation or a sequence of transformations of the other.
