You use a scale factor to find out if 2 shapes are similar.
You can also find similar angles by using a protractor or by finding other familiar angle measures already found or ones that you may already know such as: 90 degrees, 180 degrees and other ones just like those.
To scale the image up you would multiply by a whole number.
To scale the image down you would multiply by a decimal/fraction
**We will be doing a project similar to this in class. Check it out!
How I remember it:
I always think is the other half of a shape looks the same as the other if it does they are similar if it dosen't then it is not similar.
The problem with that is sometimes they are not similar even though they do look that way ^
