The coordinate of G' if triangle E'F'G' is created by dilating EFG with a scale factor of 4 about the origin is (8, -8).
<h3>The types of transformation.</h3>
In Mathematics, there are different types of transformation and these include the following:
- Reflection
- Rotation
- Translation
- Dilation
<h3>What is dilation?</h3>
Dilation can be defined as a type of transformation which changes the size of a geometric object, but not its shape. This ultimately implies that, the size of the geometric object would be increased or decreased based on the scale factor used.
Since the dilatation was centered around the origin, then we would multiply the coordinate of G by a scale factor of 4 as follows:
G = (2, -2) → G'[(4 × 2), (4 × -2)]
G = (2, -2) → G'(8, -8)
