True or false: A dilation does not change the size of a shape? Why?
False, it enlarges or reduces it.
Does the figure change size with a translation of 4 units up and 5 units right, as well as a dilation with a scale factor of 2? Why?
Yes because of the dilation.
What is the new image of G(8, 10) if it undergoes a dilation by a factor of 25?
G'(200, 250)
Is a scale factor of 1/2 and a translation a reduction, enlargement, or no change in size?
Reduction
What is the dilation factor if A(-2, 3) mapped to A'(-0.9, 1.35)?
k=0.45
Find the coordinates of A" and B" after the following glide reflection: translated by <-3, 1>, then reflected over y=-2.
What is A"(-2, -8) and B"(-1, -5)?
Dilation of 1/8 of A(-4, -6) B(1/2, 1/3) C(-5, -7)? Leave in simplest fraction form!
A(-1/2, -6/8) B'(1/16, 1/24) C'(-5/8, -7/8)
Find the coordinates of Y' when X(12, 4), Y(8,2) and Z(-4,0) are dilated by a scale factor of 1/4.
What is Y'(2, 1/2)?
What is the original image of D'(-8, -12) E'(-8, 12) F'(12, -8) if it underwent a dilation by 2?
D(-4, -6) E(-4, 6) F(6, -4)
Find the coordinates of B" when A(5, 0), B(5, 5), and C(2,4) undergo the following composition: translate (x, y)-->(x+6, y-5), then rotate counterclockwise 270 degrees.
What is B"(0, -11)?
