Geometric Transformations and Logic · Geometry

Rigid Motions and Congruence

Investigating translations, reflections, and rotations to understand how shapes remain congruent under movement.

Key Questions

  1. 1What properties of a figure remain invariant during a rigid transformation?
  2. 2How can we prove two shapes are identical using only a sequence of motions?
  3. 3Why is a reflection considered an orientation reversing transformation?
