Dilations
• In a dilation you are able to either reduce your object or enlarge it.
• If you dilate an object by 500% you will enlarge it because the 500% is actually 5 wholes and it is greater than one whole.
• Dilating your image by .5 will reduce your object because it is less than one whole.

Translations
• A translation is were you change your original coordinates by first moving your figure right or left.

Reflections
• A reflection is where you can flip your figure over the x-axis or the y-axis.

Enlargement
• In order to enlarge your figure you must have a scale factor greater than one.
• If you dilate an object by 500% you will enlarge it because the 500% is actually 5 wholes and it is greater than one whole.

Reductions
• In a reduction you have to have a scale factor less than one in order to reduce.
• Dilating your image by 0.5 will reduce your object because it is less than one whole.

How Perimeter is Affected
• The perimeter is affected the same as the scale factor ALWAYS!
• You would do your perimeter then you would say NO to oreos, and divide the new by original perimeters.
• It is easier to leave the new by old in a fraction when you divide.

How Area is Affected
• The area and scale factor will NEVER be the same as each other.
• You would say NO to oreos and divide new by original to get your answer.
• It is easier to leave your division as a fraction.

X=5
2.5
The scale factor is ½ because you would set your proportion up like so….. 10/5 = x/2.5. You would have to multiply the 10 by the ½ to get your answer which is X=5.
