K&K Dilation and Translation

Front

What is a dilation in geometry?

Back

A dilation is a transformation that alters the size of a figure, either enlarging or reducing it, based on a scale factor.

Front

What does a translation rule of (x + 4, y - 2) indicate?

Back

It indicates that the figure moves 4 units to the right and 2 units down.

Front

What happens to a figure when it is dilated by a scale factor greater than 1?

Back

The figure is enlarged.

Front

What happens to a figure when it is dilated by a scale factor less than 1?

Back

The figure is reduced.

Front

If a triangle is translated using the rule (x - 2, y + 9), how does it move?

Back

The triangle moves 2 units to the left and 9 units up.

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 scale factor is 1, what happens to the figure?

Back

The figure remains unchanged.

Front

What is the difference between dilation and translation?

Back

Dilation changes the size of a figure, while translation moves it without changing its size or shape.

Front

How do you determine if a dilation is an enlargement or a reduction?

Back

If the scale factor is greater than 1, it is an enlargement; if it is less than 1, it is a reduction.

Front

What does the notation (x + a, y + b) represent in translation?

Back

It represents a translation where the figure moves 'a' units horizontally and 'b' units vertically.
