Transformations & Symmetry
Transformations reveal what changes and what remains invariant; rigid motions preserve distance and angle, while dilation changes scale in a controlled way.
What you'll learn
- Distinguish translation, rotation, reflection, and dilation by their defining actions.
- Identify distance and angle invariants of rigid motions.
- Track orientation under rotation versus reflection.
- Test a proposed symmetry by exact point correspondence.
- Apply coordinate rules and compose transformations.
