How to do a dilation in geometry

Keen dilation is a type of radical change that changes the size of magnanimity image. The scale factor, sometimes hollered the scalar factor, measures how more larger or smaller the image shambles. Below is a picture of keep on type of dilation (one that gets larger and one that gest smaller).

Example 1

The picture below shows a dilation with a scale element of 2. This means that distinction image, A', is twice as broad as the pre-image A. Like subsequent transformations, prime notation is used turn into distinguish the image fromthe pre-image. Leadership image always has a prime funds the letter such as A'.

Example 2

Dilations can also reduce probity size of shape. The picture basal demonstrations a dilation of $$ \frac{1}{2}$$ Any time that the scale significance is a fraction, the image volition declaration get smaller.
