Answer 4

v your on

Answer 5

hint: TU is 3 times as big as QR
so ST will be 3 times as big as PQ

Answer 6

so b or a

Answer 7

think carefully about what I just wrote..

Answer 8

how big is PQ?

Answer 9

8 meters

Answer 10

good, so how big is ST?

Answer 11

it a !!!

Answer 12

yes good

Answer 19

yeah that is pretty much similarity, a 'zoom' in a by a certain amount sorta

Answer 20

corresponding sides of the figure, will be in the same ratio, or proportion (a/b

Answer 21

12/3 = 8/2 = ..

Answer 22

i can only pick one

Answer 23

you are moving from larger to smaller, so you want the inverse of that scale, the larger is 4 times larger than the smaller, or the smaller is 1/4 the larger

Answer 24

for similarity and congruence, match up the sides in ratios like that, you can solve for missing things if you need to

Answer 25

i think its a

Answer 26

th esmaller figure is 1/4 the size of the original, that is the scale, notice the ratio of the sides

2/8 = 3/12

Answer 27

reduces to 1/4

Answer 28

i got a 80

Answer 29

all the sides on the smaller one are 1/4 the size of the larger corresponding size, that is the zoom scale factor to change from small to large lengths

Answer 30

look ar the properties of similar figures, you will see that sides are in proportion
