What Does Dilation Do In Math

Dilation is one of the five major transformations in geometry dilation does not change the shape of the object from preimage to image.

What does dilation do in math. The position and size of a figure can change but not the shape. The picture below shows a dilation with a scale factor of 2. Center of dilation in the figure above we have made it easy by placing the center of dilation o in the center of the rectangle but it can be anywhere. It can become larger or smaller but the shape of the figure does not change.

Stretch dilation of a graph. A transformation in which all distances on the coordinate plane are lengthened by multiplying either all x coordinates horizontal dilation or all y coordinates vertical dilation by a common factor greater than 1. When the common factor is less than 1 the transformation is called a compression. In dilation multiply the dimensions of the original by the scale factor to get the dimensions of the image.

In general english it means to make larger. A dilation is a transformation that changes the size of a figure. A dilation is a type of transformation that changes the size of the image the scale factor sometimes called the scalar factor measures how much larger or smaller the image is below is a picture of each type of dilation one that gets larger and one that gest smaller.
