This can be a single point on a coordinate grid the middle of a polygon or any fixed point in space.

Center of dilation math definition. If the scale factor is more than 1 then the image stretches. Try this adjust the slider on the right to change the scale factor. Center of dilation is a referred to as a shrinkage in the original figure. It is a point where a dilation is based off of.

In mathematics the term center of dilation refers to a constant point on a surface from which all other points are either enlarged or compressed. Lines drawn through each point on the pre image and its corresponding image point will intersect at the center of dilation. When the scale factor is between 0 and 1 the image is shrinked. The ratio of the distance from the center of dilation to any point on the image compared to the distance from the center of dilation to the corresponding point on the pre image will result in the scale factor k.

Definition of dilation dilation is a similarity transformation in which a figure is enlarged or reduced using a scale factor. All dilations begin with a center. Dilation of a polygon a transformation in which a polygon is enlarged or reduced by a given factor around a given center point. The center of dilation is a fixed point in the plane.

If the scale factor is between 0 and 1 then the image shrinks. Drag the center point o. Based on the scale factor and the center of dilation the dilation transformation is defined. From that center of dilation the preimage the mathematical element before scaling is enlarged inverted or shrunk to form the image.

When the scale factor is greater than 1 the image is a streched. It is defined as the fixed point in a plane where all points are either expanded or contracted. 0 without altering the center. If a center of dilation is the center of a circle with radius 5 and is under a dilation with a scale factor 2 then the radius would be 10.

But in mathematics it means to make larger or smaller. The center of dilation and the scale factor comprise the two properties of a dilation.
