What is the coordinate notation for a translation 9 units right and 3 units down?

Back

(x, y) --> (x + 9, y - 3)

Front

Is a dilation with a scale factor of 2 a reduction?

Back

False

Front

What transformation occurs from triangle ABC to triangle A'B'C'?

Back

Reflection across the x-axis

Front

What transformation occurs from point C to point D?

Back

Front

Write the rule for the translation that moves a point 2 units right and 1 unit down.

Back

(x,y) --> (x + 2, y - 1)

Front

What is the definition of a translation in geometry?

Back

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

Front

What does a scale factor greater than 1 indicate in a dilation?

Back

It indicates an enlargement of the figure.

Front

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

Back

Front

What is the effect of a reflection across the y-axis on the coordinates (x, y)?

Back

(-x, y)

Front

What is the effect of a 180° rotation on the coordinates (x, y)?
