Explanation:
The term "variant" means "it changes" or "it moves location".
So "invariant" means it stays fixed in place.
The translation vector is the same as writing the rule
. It says to shift every (x,y) point 1 unit to the right and 3 units up. The key to this is the "every". There isn't a point left out that the translation doesn't touch. No points stay fixed in place. <u>There are no invariant points</u>.
In contrast, if we were to do a dilation, then the invariant point is the center of the dilation. Everything either shrinks or enlarges with respect to this fixed center point. Another example would be a rotation where the center of rotation stays fixed. Unfortunately, translations do not have this property of having an invariant fixed point.
