Given
- Triangle DGF, with vertices D(- 2, 0), G(2, 0), F(2, - 2),
- Scale factor r = 1.5.
Solution
Triangle DGF is plotted, blue figure.
Find the coordinates of the image using the rule:
- D' = (1.5*(-2), 1.5*0) = (-3, 0),
- G' = (1.5*0, 1.5*2) = (0, 3),
- F' = (1.5*2, 1.5*(-2)) = (3, - 3).
The points added to same plot, red figure.
