Flashcard: Translation & Dilation

Front

What is translation in geometry?

Back

Translation is a transformation that moves every point of a figure the same distance in a specified direction.

Front

What does it mean when a scale factor is less than one in dilation?

Back

When the scale factor is less than one, the dilation is a reduction, making the figure smaller.

Front

How do you express a dilation with a scale factor of 3?

Back

The algebraic notation for a dilation with a scale factor of 3 is (x, y) goes to (3x, 3y).

Front

What is reflection in geometry?

Back

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

Front

What is the scale factor in a dilation?

Back

The scale factor is a number that describes how much a figure is enlarged or reduced during a dilation.

Front

If a figure is translated 5 units down and 4 units to the right, what is the new position of point (2,3)?

Back

The new position of point (2,3) after translation is (6, -2).

Front

What is the difference between translation and rotation?

Back

Translation moves a figure without changing its orientation, while rotation turns a figure around a fixed point.

Front

What happens to a figure during a dilation with a scale factor of 1?

Back

A dilation with a scale factor of 1 leaves the figure unchanged in size.

Front

If a figure is enlarged by a scale factor of 2, what happens to its dimensions?

Back

All dimensions of the figure are doubled when enlarged by a scale factor of 2.

Front

What is the result of reflecting a point (x, y) over the x-axis?

Back

The result of reflecting a point (x, y) over the x-axis is (x, -y).
