Question

If 'n' is scale factor to draw a dilation, then choose the correct options.

• A. If n > 1, then dilation is enlarged than the original.
• B. If 0 < n < 1, then dilation is reduced than the original.
• C. If n = 1, then dilation is equal to the original.
• D. If n > 1, then dilation is reduced than the original.

Answer 1

Answer: (A), (B), (C)

The correct options are
A If n > 1, then dilation is enlarged than the original.
B If 0 < n < 1, then dilation is reduced than the original.
C If n = 1, then dilation is equal to the original.

The method of drawing enlarged or reduced similar figure is called dilation.
$Scalefactor=\frac{Sidelengthofdilatedfigure}{Sidelengthoforiginalfigure}$

If side length of dilated figure > original length,
then scale factor > 1 and dilation is enlarged than original.

If side length of dilated figure < original length,
then scale factor < 1 and dilation is reduced than the original.

If side length of dilated figure = original length,
then scale factor = 1 and dilation is equal to the original.
