ms sue will you help me
if my coordinates are A o,4 B 4,4 C 2,0 D 0,0
THE DILATION IS A' 0,2 B' 2,2 C' 2,0 D' 0,0
what is the scale factor?
I have no idea. My math skills stop at about 8th grade.
HELPP
I THINK IT IS 2 NM
To find the scale factor of a dilation, you need to compare the corresponding side lengths or distances between the original figure and the dilated figure. In this case, we can compare the distances between point A and point A', which can be calculated using the distance formula.
The distance formula for two points (x1,y1) and (x2,y2) is given by:
d = sqrt((x2 - x1)^2 + (y2 - y1)^2).
For the original figure:
Coordinates of A: (0, 4)
Coordinates of A': (0, 2)
Using the distance formula to find the distance between A and A':
d = sqrt((0 - 0)^2 + (2 - 4)^2) = sqrt(0 + 4) = sqrt(4) = 2.
Therefore, the distance between A and A' is 2 units.
Similarly, calculate the distance between B and B', and compare it with the distance between A and A'. If they are equal, it means the scale factor is 1. If the distance between B and B' is twice the distance between A and A', the scale factor is 2. If it's three times, the scale factor is 3, and so on.
Repeat the same process for points C and C', and D and D' to check if the distances are proportional.
If all the distances are equal, then the scale factor is 1. If they are not equal, calculate the ratio of any two corresponding distances to find the scale factor.
