Question

Can anyone help?

Answer 1

What is it you need help with?

Answer 2

This question

Answer 3

I'm sorry I can't help I'm not very good with geometry. Sorry :(

Answer 4

Know any one that can

Answer 5

Maybe you can ask satellite :)

Answer 6

tag them @TypnoEchosis

Answer 7

So the : between the letters and numbers means we're doing ratios right?

Answer 8

yees

Answer 9

Alright, so let's find the number ratio of line SR

For SR, which coordinate changes on the (x,y)? The x or the y?

Answer 10

I honestly have no idea.

Answer 11

So for line SR, we take the coordinate of S and R.

S is (1, 5) and R is (7, 5)

With the basic (x, y), the x changes. See how that is now?

Answer 12

Yes i do. You added 6 to the x coordinate

Answer 13

Correct, and good job! We just found the first part of our SR:SP ratio. Like you said, it's 3.

Now, for the SP part of the ratio.

We have S at (1,5) and P at (1,1). Using (x,y), does the x or y change? And by how much?

Answer 14

Lol wait, you said it was 6, mb, I mean 6

Answer 15

i know what you meant. The Y changes by subtracting 4.

Answer 16

Right, so the SP part is 4

So now we have the SR:SP ratio of 6:4. Would you know how to simplify that?

Answer 17

Yes it would be 3:2

Answer 18

Yep!

Since SR:SP is 3:2, I think we can get rid of 3 of these answers :D

Do you want to do the other triangle to make sure, or you got it?

Answer 19

It's ok I think I got it now! Do you mind helping me with another?

Answer 20

Sure!

Answer 21

Okay 1 min

Answer 22

Rectangle*
Lol oops, I'm tripping

Answer 23

I actaully have 2 more, here is 1

Answer 24

He looks like he's doing Pythagorean theorem. Are you familiar with that?

Answer 25

Yes

Answer 26

So the first proof says ABC is similar to BDC

Would you agree that if I cut a triangle perfectly in half, it would be similar in a way?

Answer 27

yes

Answer 28

Ok, I see the answer now. Let's make this easier. Starting with step 1 he says his justification is

Angle ABC = Angle BCD
Angle BCA = Angle DBC

Would you agree with that or no? (Remember, if a angle is 90 degrees, it will have a square angle)

Answer 29

no

Answer 30

Right

Because ABC is a right angle and BCD looks acute to me
BCA is acute and DBC is also acute, but the first proof didn't match

Looking at answer choice for the first justification, they say change it to

ABC = BDC and BCA = DBC

^ Both those are right angles ^ Both of those are acute

So that would seem like a good answer choice

Answer 31

That make sense?

Answer 32

Yes! Which anwser choice is it?

Answer 33

We can say B since that's a possible choice

Answer 34

Okay thank you!
