Front

What is a dilation in geometry?

Back

A dilation is a transformation that alters the size of a figure but maintains its shape. It is defined by a scale factor.

Front

What does a scale factor greater than 1 indicate?

Back

A scale factor greater than 1 indicates an enlargement of the figure.

Front

What does a scale factor less than 1 indicate?

Back

A scale factor less than 1 indicates a reduction of the figure.

Front

What is the rule for reflecting a point over the y-axis?

Back

The rule is: @@(x, y) ightarrow (-x, y)@@.

Front

What is the output of a transformation?

Back

The output of a transformation is the figure after the transformation has been applied.

Front

What does a reflection preserve?

Back

A reflection preserves congruence.

Front

What is the difference between a transformation and its image?

Back

A transformation is the process applied to a figure, while the image is the result of that transformation.

Front

What is the rule for reflecting a point over the x-axis?

Back

The rule is: @@(x, y) ightarrow (x, -y)@@.

Front

What is the effect of a dilation with a scale factor of 1?

Back

A dilation with a scale factor of 1 results in no change to the size of the figure.

Front

What is the definition of congruence in geometry?

Back

Congruence means that two figures have the same shape and size.
