Question

Determine whether the polygons with the given vertices are similar. Support your answer by describing a transformation.

V(3,2) W(8,2) X(1,5)
R(6,4) S(16,4) T(3,15)

I think they are not similar because V and W are dilated by 2 and X is dilated by 3. They need to be dilated by the same factor to be similar.

Answer 1

agree

Answer 2

V to W = sqrt (25+0) = 5
R to S = sqrt (100+0) = 10

W to X =sqrt(49+9) = sqrt(58)
S to T = sqrt(169+121) = sqrt (5*58) oh my :(, not twice, would be sqrt 4*58 if similar

Answer 3

V, W, and X are part of one polygon, and R, S, T are part of another polygon. So why is V to W calculated?

Answer 4

because if they were similar
then if V to W is 5
and R to S is 10
then if similar
W to X must be HALF of S to T
It is not, it is sqrt 5 times

I know which sides to compare because I drew a quick sketch of the two figures.
