Answer 9

how ?

Answer 10

actually..hmm I guess you could use AA, nvm

but SSS works too

Answer 11

What is it?? :(

Answer 12

you mean SAS works too ?

Answer 13

no SSS

Answer 14

that page I posted explains

Answer 15

from that page

"SSS Similarity Theorem


This theorem states that if the sides of two triangles are in proportion, then the triangles are similar."

Answer 16

so, it's SSS?

Answer 17

no jim, all 3 pairs of sides need to form a proportion for SSS to work

Answer 18

SSS would have been my first choice....but AA works as well (you need to do a bit of work, not much though)

Answer 19

actually you just need 2 pairs and SSS works

Answer 20

This is worth a lot of points... :(

Answer 21

all 3 pairs of sides need to have same ratio, jim. only 2 side ratios matching wont do for SSS

Answer 22

hmm this page is odd, they use SSS first, then SAS

nvm, i guess it's not accurate

go for AA

Answer 23

good point ganeshie8

Answer 24
