Front

Define 'Transformation' in geometry.

Back

A transformation is an operation that moves or changes a shape to create a new shape.

Front

What is a 'Reflection' in geometry?

Back

A reflection is a transformation that flips a shape over a line, creating a mirror image.

Front

What is a 'Rotation' in geometry?

Back

A rotation is a transformation that turns a shape around a fixed point at a certain angle.

Front

What is a 'Translation' in geometry?

Back

A translation is a transformation that slides a shape from one position to another without turning or flipping it.

Front

What does 'Congruent' mean in geometry?

Back

Congruent means that two shapes are the same size and shape.
