Geometry Help

Answer 1

@JakeV8, please help me later when u able to

Answer 2

yuk, that question is awful :(

Answer 3

I know, ya

Answer 4

I got totally zero, see how bad i am ?

Answer 5

ok, so let's try the first one...

First of all, for the whole problem, the two similar shapes are ABCD ~ QRST... so it's like some sort of matching game... anytime you have a side on one shape, the corresponding side on the other shape is the side with the letters in the same place... so AB ~ QR, etc.

Does that make sense?

A) says TQ is 10 inches. TQ is the last letter and the first letter of the 2nd shape. So the corresponding side on ABCD is also the last & first letters... DA.

Answer 6

ok

Answer 7

The problem gives DA length as 2. So side TQ is 10, and the corresponding part on ABCD is DA and it measures 2... so TQ is 5 times larger than DA. So if TQ is 10, the scale factor is "5"

Answer 8

Yeah, it is too complicated probs

Answer 9

so, for A in the right column, it has a scale factor of 5. So you put "A" in the block in the left column beside the number 5 in the middle column. That's what you have, so you got that one right :)

Answer 10

ok, alphabets corresponding sides, whatever it is in there, made me confuse, so sorry about it

Answer 11

I meant, how will i match other, and if i got any kind of probs like this, how do i solve those?

Answer 12

does that d would be the ST, 16

Answer 13

?

Answer 14

it is ok @JakeV8 if u cant cuz u did alot :) i m fine with it

Answer 15

@Faman39 I'm sorry, somehow this browser tab got disconnected from the rest of my many open tabs, so I didn't even see that it was still up.

For ST = 16, it corresponds to CD which they told you was 8. So ST is twice as large, or a ratio of 2.

Answer 16

It is totally ok @jakev8, so it is b ?

Answer 17

i meant, 16 st = 2

Answer 18

ST = 16 is twice CD = 8... That chart is making my head hurt!

I think in the final block... last row, you put "D" because item (D) with ST = 16 matches up to the "Term" 2 in the middle column, last row.

Answer 19

I m so sorry @JakeV8 , if it is bothering u please dont do it, i m ok

Answer 20

no, it's just a really hard way to deal with a reasonably easy topic (similar shapes have a constant ratio between corresponding sides)

Answer 21

thats y, i hate geometry :)

Answer 22

Now, i m sure i m gonna fail that test

Answer 23

If I gave you shape A as a square with sides length 4, and square B with sides length 8, you would have no problem seeing that square B's sides are twice as long as those in square A.

The ratio of side lengths is easy, even for you ;) you just compare as a fraction or ratio.

But the way that problem is written, even though I know the material, I can barely keep straight how to answer.

Answer 24

Ok, i will try

Answer 25

ok, here's another one... the third row. It says QR is 2 inches, and QR corresponds to AB in ABCD. AB is listed as 5 inches.

So the comparison is AB : QR <<<--->>> 5 inches : 2 inches

So to multiply to get from 5 inches down to 2 inches, you need to multiply by 0.4
(you could find that by dividing 2/5 = 0.4)

In the other examples, shape QRST was larger, so you multiplied by a number like 2 or 5 to convert from shape ABCD up to the larger QRST. But in the 3rd row, you multiply by a number smaller than 1... that shrinks ABCD down to the smaller QRST.

Answer 26

Overall, the responses should be B, A, C, and D going down the rows.

Answer 27

Thank you so much @JakeV8 !!!

Answer 28

Good luck!

Answer 29

Thank you :) i will try to understand which u taught me
