Module 1 Day 1 Leaping Lizards Translation Demo

① This example shows a “leaping lizard” undergoing translation, rotation, and reflection on the plane. ② Key concepts: rigid motions, translation vectors, rotation angles, reflection axes, and congruence of figures. ③ Construction highlights: points A‑T and images pic1, pic2 are created in GeoGebra; the “Translate”, “Rotate”, and “Reflect” commands produce successive lizard positions, while the “Polygon” command links key points to outline the lizard. ④ Suitable for middle‑school geometry transformations, high‑school analytic geometry review, and teacher‑made interactive lessons.
