What is the rule for a 180° rotation?

Back

The rule for a 180° rotation is: (x, y) → (-x, -y).

Front

Back

To rotate a figure, apply the right rule to the point.

Front

What is a reflection in geometry?

Back

A reflection is a transformation that flips a figure over a line.

Front

What is dilation in geometry?

Back

Dilation is a transformation that changes the size of a figure but not its shape.

Front

What is the effect of a translation on the coordinates of a point (x, y)?

Back

A translation affects the coordinates by adding or subtracting values to/from x and y.

Front

What is the difference between rotation and reflection?

Back

Rotation turns a figure around a point, while reflection flips it over a line.

Front

What is the scale factor in dilation?

Back

The scale factor is the ratio of the size of the new figure to the size of the original figure.
