What is translation in geometry?

Back

Translation is a transformation that slides a shape from one position to another without turning it.

What is reflection in geometry?

Back

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

What is dilation in geometry?

Back

Dilation is a transformation that changes the size of a shape but keeps its proportions the same.

Front

What does it mean when a shape is enlarged?

Back

Enlargement occurs when the scale factor of a dilation is greater than one, making the shape larger.

What does it mean when a shape is reduced?

Back

Reduction occurs when the scale factor of a dilation is less than one, making the shape smaller.

What is the scale factor in dilation?

Back

The scale factor is a number that describes how much a shape is enlarged or reduced during dilation.
