What is a reflection in geometry?

Back

A transformation that flips a figure over a line, creating a mirror image.

Front

What is a translation in geometry?

Back

A transformation that slides a figure from one position to another without turning it.

Front

What is a dilation in geometry?

Back

What is the effect of reflecting a point across the y-axis?

Back

The x-coordinate changes sign, while the y-coordinate remains the same.
