Transformation- Dilation

When you dilate a figure the size & location changes according to the scale factor.
The shape of the figure never changes no matter what. When we zoom into A photo the
photo may get bigger. Zooming into a photo relates to dilation by making the
photo bigger or smaller which the scale factor also do. When you have a scale factor of
1.5 the bigger is gonna get bigger, Now on the other hand when you have something less than 1
like 0.5 for example, the figure will get smaller. The differences between translations and dilations is that dilations could change in size and locations NOT in SHAPE !!! Translations is a sliding, it slides left,right,up or down. When you multiple by 1/3 it is the same as dividing by 3.
For example, lets take a look at 9, if you take 1/3 its gonna be 3 & if you divide it by 3 its gonna be 3 also.

Transformation- Translation

When you look at two figures the only way possible
that you can tell which one is the transformation
is by looking at the points & if it has an apostrophy then it
is the transformation.
Now when the transformation figure is done, The new
name it is giving is prime after the name.
For example - A is the original & A prime is the transformation.
Well to begging with translation, the word(s) i would use in order
to describe translation is location. The reason i would use location is because
translation only focuses on moving its location, it does not change shape or size.
& just in case your wondering, A translation figure will never ever change in shape.
The reason it won't is because when you translate something your just moving the location
from where it is at.
The best way for me to translate a figure with out a coordinate grid is to just fold the paper
that you are using. Thats the best way i can think of.
