Understanding Translations: What Changes and What Stays the Same

This lesson covers the concept of translating a figure, specifically a parallelogram, and examines what changes and what remains constant during this transformation. Key vocabulary such as congruent line segments, congruent angles, and parallel lines are reviewed. The process of translating a parallelogram is demonstrated, and the use of prime notation is explained. The lesson investigates the congruence of line segments and angles after translation, confirms the preservation of parallelism, and discusses the change in position. New vocabulary terms related to geometric transformations are introduced.
