Question 1003846: The vertices of a triangle are A(8,-24), B(8,-8) and C(16,-8).If the triangle is dilated by a scale factor of 1/4, what will be the coordinates of A'?
Answer by Edwin McCravy(20056)   (Show Source):
You can put this solution on YOUR website! The vertices of a triangle are A(8,-24), B(8,-8) and C(16,-8).
If the triangle is dilated by a scale factor of 1/4, what will
be the coordinates of A'?
Since you did not state the center of dilation, I will
assume you meant the center of dilation to be the origin.
A(8,-24), B(8,-8) and C(16,-8)
In that case, we multiply all the coordinates of
A(8,-24), B(8,-8) and C(16,-8)
by 1/4, and get
A'(2,-6), B'(2,-2) and C'(4,-2)
We draw the dilated triangle A'B'C' in red also, and
green lines from the origin through the coordinates:
I know you just wanted A' but you need to understand what's
going on, not just a cookbook way to get an answer. It's
very hard to learn math the cookbook way without understanding
what's going on. Understanding is what makes math easy.
