Sal interprets a scale factor to determine if a scale copy will be larger or smaller than the original figure.

• this makes no sense to me i feel so stupid
• i am confused
• me to
• I am still unsure about the scale factor... Could you please explain it in a simpler way please? My brain is not functioning today. (¬_¬")
• the scale factor is basically like if you have 1 side that has a length of 3 and a side 2 that has a length of 9, what do you multiply by side 1 to get side 2.

• What is a scale factor
• Scale factors are like what is seen on a copy machine or on your computer. You can reduce the size of your screen by 200% (scale factor of 2) or 50% (scale factor of 1/2). Similarly, you can make copies that are smaller or larger than the original. Scale factors do just this, make something bigger or smaller than the original, but you could also still have a scale factor of 1 if you want to make a exact copy of the original.
• when you draw the line do you just pick how big you want it or does it have to be a certain size.
• i think its any size you want
• In the last practice theres no way to tell if you have to use whole numbers or fractions this is stupid.
• Actually, that is not true. You use fractions when you are scaling down, and whole numbers when scaling up.

Hope this helps!
