Explanation:
What is dilation means?
Dilation is a transformation of the plane where each point, P, of the plane is assigned a new point such that the length of QP'=n*QP. In a plane, transformation in which each point on the image lies on the same line as the corresponding point on the pre-image and a fix point called the center of dilation, and results in an enlargement or reduction of a figure.
Q is the center of dilation.
N is the scale factor.
A dilation moves each point, other than the center of dilation, a specific distance based on the value of n.
Center of dilation in a dilation, the fixed point that is collinear with each point on the pre-image and the corresponding point on the image.
Scale factor is a dilation, the constant ratio between the distance from the center of dilation and a point on the image and the distance from the center of dilation and corresponding point on the pre-image.
