7.01 Dilations
Interactive practice questions
$\triangle KLM$△KLM has vertices $K\left(-10,-5\right)$K(−10,−5), $L\left(9,6\right)$L(9,6), and $M\left(8,-8\right)$M(8,−8) is dilated by a factor of $0.4$0.4 using the origin as the center of dilation.
Identify the following coordinates after the dilation.
-
$K'$K′$=$=$\left(\editable{},\editable{}\right)$(,)
-
$L'$L′$=$=$\left(\editable{},\editable{}\right)$(,)
-
$M'$M′$=$=$\left(\editable{},\editable{}\right)$(,)
$L'M'N'O$L′M′N′O is the dilation of $LMNO$LMNO. Determine the scale factor.
Dilate the figure using the transformation $\left(x,y\right)$(x,y)$\to$→$\left(\frac{1}{5}x,\frac{1}{5}y\right)$(15x,15y) with the origin as the center of dilation.
Dilate the figure using the transformation $\left(x,y\right)$(x,y)$\to$→$\left(3x,3y\right)$(3x,3y) with the origin as the center of dilation.
