Front

What is the algebraic representation of a dilation by a scale factor of 3?

Back

(x, y) → (3x, 3y)

Front

What is the difference between a translation and a reflection?

Back

Translations slide a figure while reflections flip a figure.

Front

What does it mean to preserve the congruence of an image?

Back

To remain the same size.

Front

What is the algebraic representation for a rotation of 180° around the origin?

Back

(x, y) → (-x, -y)

Front

What type of dilation occurs when the scale factor is greater than 1?

Back

An enlargement.

Front

What is a translation in geometry?

Back

A transformation that slides a figure to a new position without changing its shape or size.

Front

What is a reflection in geometry?

Back

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

Front

What is a rotation in geometry?

Back

A transformation that turns a figure around a fixed point.

Front

What is a scale factor in dilation?

Back

A number that describes how much a figure is enlarged or reduced.

Front

What happens to the coordinates of a point (x, y) during a dilation by a scale factor of k?

Back

The new coordinates are (kx, ky).
