The coordinates of the image of the dilation are [tex]R' = (-3.75,2.25)[/tex], [tex]S' = (2.25,3)[/tex] and [tex]T' = \frac{3}{4} \times (2.25,4.5)[/tex]
Dilation
Dilation involves changing the size of a shape
Coordinates
The coordinates of triangle RST are given as
[tex]R = (-5,3)[/tex]
[tex]S = (3,4)[/tex]
[tex]T = (3,-6)[/tex]
The scale factor is given as:
[tex]k = \frac 34[/tex]
The rule of dilation using the origin as the center of dilation is:
[tex](x,y) \to k(x,y)[/tex]
So, we have:
[tex]R' = \frac{3}{4} \times (-5,3)[/tex]
[tex]R' = (-3.75,2.25)[/tex]
[tex]S' = \frac{3}{4} \times (3,4)[/tex]
[tex]S' = (2.25,3)[/tex]
[tex]T' = \frac{3}{4} \times (3,6)[/tex]
[tex]T' = \frac{3}{4} \times (2.25,4.5)[/tex]
Hence, the coordinates of the image of the dilation are
[tex]R' = (-3.75,2.25)[/tex], [tex]S' = (2.25,3)[/tex] and [tex]T' = \frac{3}{4} \times (2.25,4.5)[/tex]
