What is the scale factor of dilation? 1 over 2 1 over 3 1 over 4 1 over 5

The scale factor of dilation is

Step-by-step explanation:

To find the scale factor of dilation, we can look at the length of the sides compared to the sides of the new.

In the case of this problem, the larger triangle KJH is the original and the smaller triangle K'J'H' is the new.

First, lets look at side KJ. It has a measure of 4 units.

And now K'J', which has a measure of 1 unit

Side JH has a measure of 4 units

J'H' has a measure of 1 unit

Side HK has a measure of 4 units diagonally

H'K' has a measure of 1 unit diagonally

To find the scale factor of dilation, we divide the new side length by the original. When done for each of these, the result is
