Answer:
Dilation.
Step-by-step explanation:
From the given picture , it can be seen that the size of trapezoid P'Q'R'S' is decreased from trapezoid PQRS .
Reflection , rotation and translation are rigid motions that produces congruent images and do not change the size of the shapes.
But dilation is not a rigid motion because it changes the size of the shape by using a scale factor.
Hence, the transformation maps trapezoid PQRS onto trapezoid P'Q'R'S' is "Dilation".
Answer:
-4
Step-by-step explanation:
by finding the exact value.
9:2 is equivalent because it is dividing each side by the same amount. 18 divided by 2 is 9 and 4 divided by 2 is equal to 2, so 9:2 would be equivalent to 18:4.
