Front

A dilation is given by the transformation (x, y) → (2.5x, 2.5y). What is the scale factor?

Back

Front

When you rotate 180 degrees the (x, y) becomes?

Front

Write a rule for the translation: (x, y) ---> ___________

Front

What is a translation in geometry?

Back

A translation is a transformation that moves every point of a shape the same distance in the same direction.

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 the effect of a 90° clockwise rotation on the point (x, y)?

Back

(y, -x)

Front

What is the effect of a 90° counterclockwise rotation on the point (x, y)?

Back

(-y, x)
