Part A:
1 - yes, dilation
2 - no, shaded is 90 degree cc of non shaded
3 - yes dilation
Part B:
For part B, just plot the points.
For the dilated figure, multiply the x and y coordinates by 4.
Ex: V(-1, -1) --> V'(-4, -4)
It is an enlargement since the scale factor is greater than one.
Part C:
unshaded: X(-4, 4) Y(-4, -4) Z(4, -4)
Shaded: X(-1, 1) Y(-1, -1) Z(1, -1)
From shaded to unshaded it is 4, since nonshaded side length are 4x longer.
From unshaded to shaded it is 1/4 because shaded side lengths are 1/4 that of unshaded.
