# Similarity and Transformations

### example 1 :

### When two figures are similar the second figure has to be in poportion with the first figure.

** When a figure's side is missing:**

** Step 1: Set up your proportion and gather you numbers. **

** Step 2: Cross multiply the two numbers that are both there, and then divide that product by the number that is left on the other side of your proportion/figure. The number you end up with is the missing side length. **

** If the proportions add upp and are equal the figures are similar **

Determining If the Figures are similar

**Step 1: ****Set up your proportion and gather you numbers. **

** ****Step 2: Cross multiply the two numbers that are across from each other, and then. Then you reduce your numbers, if they are not the same then they are similar. **

** NOTE: If you do the proportion and the numbers don't add up then the first time try one more to be sure.**

** If two proportions are equal then most likely are all the same and the figures are similar. **
