Question

∆ABC is similar to ∆PQR. AB¯¯¯¯¯ corresponds to PQ¯¯¯¯¯, and BC¯¯¯¯¯ corresponds to QR¯¯¯¯¯.
If the length of AB¯¯¯¯¯ is 9 units, the length of BC¯¯¯¯¯ is 12 units, the length of CA¯¯¯¯¯ is 6 units, and the length of PQ¯¯¯¯¯ is 3 units, then the length of QR¯¯¯¯¯ is ______(fill in) units and the length of RP¯¯¯¯¯ is ________(fill in) units.

Answer 1

do you have a picture?

Answer 2

There is no picture... :(

Answer 3

ok first thing i would do is draw out your triangles and fill in the known lengths

Answer 4

if you do that you will see that AB is 9 and PQ is 3 being similar triangles all the angles will work with that ratio. So doing 9/3 which ='s 3 you would divide the other angles by 3 so BC is 12 so divide that and you find QR

Answer 5

I'm not sure where to go from this, lol.

Answer 6

do you need me to draw it out or did that make sense?

Answer 7

Wait, I do not understand?

Answer 8

ok ill draw it out one moment

Answer 9

Alright, thank you.

Answer 10

So I just cut the proportions in half?

Answer 11

thirds, i set the problems up for you here does it make sense now?

Answer 12

Yes, I will let you check my answers in a moment.

Answer 13

Yes?

Answer 14

WOW. No the second one should be two, right? Wow me.

Answer 15

nope. Think of it like the last problem this is all just proportions. Think the triangle on the right is 1/3 the size of the other one and you just divide all the lengths on the left by 3 so QR = 4 and Rp = 2

Answer 16

wait yes to that lol

Answer 17

Welp, I feel dumb, lmao.

Answer 18

Sweet, I passed!

Answer 19

XD we all make those mistakes at one point or another

Answer 20

100%?

Answer 21

I blame me going to bed at 2 and waking up at 6.

And no, I got 4/5 correct though. It was from a question I tried to do on my own, lol.

Answer 22

lol ok if you want to redo it at any time for a 100 ill help

Answer 23

If only I could lol. Auto submits, no retries unless I fail. :(

Answer 24

oh wow my class I can redo up to 3 times

Answer 25

Lucky. :(
