Identify whether a dilation of ratio is a reduction, an enlargement, or a congruence.
Hint
Greater than 1, this ratio is.
Answer
It's an enlargement.
If A is at (-5, 7), where would A' be located under dilation about the origin of ratio 4?
Use the force (of multiplication), Luke.
(-20, 28)
If HI = 12, what is the length of H'I' under dilation about J of ratio ?
Use multiplication and you'll be more accurate than the Sand People.
H'I' = 4
If KL = 6 and MN = 9, which is the preimage if the scale factor is ?
The preimage is pre the image. How meta.
MN
The preimage QR = 15 while the image Q'R' = 5. What is the scale factor of this dilation?
Q'R' is a little short for a stormtrooper. Maybe it was a stormtrooper once, but it's been reduced.
Identify the coordinates of the center of dilation if the scale factor is 3.
(7, 4)
Find the value of m.
Algebra (and knowing the scale factor) is your only hope.
m = 5
Find the value of n.
Algebra will help you. The force will not.
n = 3
