Question

Nancy drew parallelogram ABCD as shown.

Parallelogram ABCD with coordinates A(2, 3), B(5, 3), C(7, 5), and D(4, 5).

On the same grid she will draw parallelogram PQRS similar to parallelogram ABCD with the ratio of corresponding side lengths PQ and AB equal to 2 : 1. If the coordinates of vertex P are (-4, 4), what could be the coordinates of vertex Q?

(-8, 8)

(-4, 10)

(8, 3)

(2, 4)

Answer 1

The only thing that is important is proportionality, i.e. the second figure is twice as big (in every linear way) as the first. Therefore...you know the distance between P and Q. Only one of those points will be the correct distance.

Answer 2

ask Nancy to solve it…

Answer 3

-_-

Answer 4

do you know how to do it or not

Answer 5

ya. read the question 4 times

Answer 6

How long is AB?
