Geometric Transformation: Translation and Scaling

This example demonstrates how key geometric objects change under translation and a related scaling/affine transformation, visualizing the correspondence between the original configuration and its transformed image. It centers on geometric transformations (Translation/Scaling), matrix-based affine mapping, and the way lines and special points map to new positions while preserving the transformation rules. Construction-wise, it uses GeoGebra’s ApplyMatrix command together with Line to define the transformation and generate image objects: original points/lines (e.g., a, A, C, D, f, r1, Fr, b) and their transformed counterparts (such as C', D', f', r1', Fr', etc.). The clear “before vs. after” setup makes it suitable for students studying transformations in coordinate geometry and for educational use in middle school advanced tracks through early university level.
