Front

What is dilation in geometry?

Back

Dilation is a transformation that alters the size of a figure but keeps its shape the same, using a scale factor.

Front

What is the scale factor in dilation?

Back

The scale factor is a number that scales, or multiplies, the dimensions of a figure during dilation.

Front

If the scale factor is 3, what happens to the side lengths of a figure?

Back

The side lengths become 3 times larger.

Front

What is the relationship between the original perimeter and the new perimeter after dilation?

Back

The new perimeter is equal to the original perimeter multiplied by the scale factor.

Front

If a figure is dilated by a scale factor of 1/2, what happens to its size?

Back

The figure is reduced to half its original size.

Front

True or False: The perimeter of a figure changes by the same scale factor as its side lengths during dilation.

Back

True.

Front

What happens to the coordinates of a point (x, y) when dilated by a scale factor of 3?

Back

The new coordinates become (3x, 3y).
