Similarity

What I know about it:
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 ^=
