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.
