Question

The table below shows the coordinates of triangle RST and the coordinates of R’ in triangle R’S’T’.
Triangle R’S’T’ is a dilation of triangle RST.

Triangle Triangle
RST R'S'T'

R (-2,-3) R' (-6,-9)
S (0,2) S' ?
T (2,-3) T'


Part A

What are the coordinates of point S’ and point T’?

Answer
S' = (____,____)
T'= (____,____)

Answer 1

Okay, first put R,S,T, R' in a cartesian plan

Answer 2

ok

Answer 3

and then get all segments length, can you do it?

Answer 4

i got 0,6 for s' and for t i think is 6,-9 is that right ?

Answer 5

T'

Answer 6

?????

Answer 7

You should get something like this: http://puu.sh/rF54

Answer 8

Then you put S' in the graph: http://puu.sh/rF73

Answer 9

i noe how to plot the points but was my answer right ?

Answer 10

Then since it's a dilation, you'll need to find the center.

Answer 11

S'=0,6 T' =6,-9 Is that right ?

Answer 12

since the dilation from R to R' just multiples all components by 3; we should assume thats what we need to do to the rest of the points as well

Answer 13

S'=0,6 T' =6,-9 Is that right ?

Answer 14

looks right to me; im assuming the dilation is from the origin, since it is not stated

Answer 15

Okay Thanks :)

Answer 16

yep
