Exploring Translations, Reflections, and Rotations in Geometry

What is a translation in the context of transformations?

• Rotating a shape around a point

• Moving a shape without changing its size or orientation

What does it mean if a movement is described as 'rigid' in geometry?

• The shape can expand or contract

• The shape loses its original properties

• The shape becomes distorted

• The shape's size and angles are preserved
