Transformations!

Front

What is a transformation in geometry?

Back

A transformation is a change in the position, size, or shape of a figure.

Front

What is a translation?

Back

A translation moves a shape from one place to another without changing its size, shape, or orientation.

Front

What is a reflection?

Back

A reflection flips a shape over a line, creating a mirror image.

Front

What is a rotation?

Back

A rotation turns a shape around a fixed point at a certain angle.

Front

What is dilation?

Back

Dilation is a transformation that changes the size of a shape but keeps its proportions the same.

Front

What does it mean to reflect across the y-axis?

Back

Reflecting across the y-axis means flipping a shape over the vertical line (y-axis), changing the sign of the x-coordinates.

Front

What does it mean to reflect across the x-axis?

Back

Reflecting across the x-axis means flipping a shape over the horizontal line (x-axis), changing the sign of the y-coordinates.

Front

What is the scale factor in dilation?

Back

The scale factor is the number that tells how much larger or smaller a shape will be after dilation.

Front

What is the difference between translation and reflection?

Back

Translation moves a shape without changing its orientation, while reflection flips it over a line.

Front

Can a shape be both rotated and translated?

Back

Yes, a shape can be rotated and then translated, changing its position and orientation.
