Question

Geometry? What is the coordinate of D’ if triangle DEF is created by dilating DEF with a scale factor of 0.5 about the origin

Answer 1

Given the figure of the triangle DEF.

The coordinates of the triangle are as follows:

`\begin{gathered} D\colon(3,0) \\ E\colon(0,1) \\ F\colon(-2,-1) \end{gathered}`

We will find the coordinates of D' when the triangle dilated with a scale factor of 0.5 about the origin

So, the coordinates of D' will be as follows:

`D^(\prime)=0.5D=0.5\cdot(3,0)=(1.5,0)`

So, the answer will be the coordinates of D' = (1.5, 0)
