Question

The two triangles below are similar. What is the similarity ratio of ΔABC to ΔDEF?

Triangle ABC is shown with AC measuring 8 and BC measuring 12. Triangle DEF is shown with side DF measuring 4.

3:1
1:3
2:1
1:2

I'm thinking the answer is but i am not 100% sure. Please someone help me. Thank you!

Answer 4

Heyo :)

Answer 5

Is there a picture to go with this? Or do we have to draw it out?

Answer 6

We first determine which sides are congruent to each other. Triangle DEF seems to be turned on its side so we would assume that `DF is congruent to AC` while as `EF is congruent to BC`. So we see that `DF is equal to 4` and `AC is equal to 8` How would we get from 4 to 8?

Answer 7

im not sure I'm pretty terrible at this stuff.. :/ is D wrong?

Answer 8

A was my second choice btw

Answer 9

Well we are seeing the similarity from `ABC to DEF` so we would find out how 8 got to 4 instead of 4 to 8 (sorry barely realized that one). So we divide.

\(\huge\bf{\frac{8}{4}}\)

Answer 10

so then 2:1?

Answer 11

Correct :)

Answer 12

so C is the answer u sure?

Answer 13

Pretty sure ;)

Answer 14

ok thanks so much
