2) the following triangles are similar. state the postulate or theorem that proves they are similar along with the correct scale factor. a. sss~; 2: 1 b. sas~; 2: 1 c. sss~; 3: 2 d. sas~; 3: 2

Hello!

First you have to find the ratio

To find this you put the sides of the triangles in a ratio and simplify it

Make sure you do the same side on each triangle

12 : 8 
6:4
3:2

The ratio is 3:2

We do not know all three sides so we can use the SSS postulate

This tells use the answer is the SAS postulate with a ratio of 3:2

The answer is D) SAS; 3:2

Hope this helps!
