Question

.

Answer 1

@AccessDenied I have another question :)

Answer 2

interesting timing, i just got on!

Answer 3

Oh seriously? XD Wow

Answer 4

Those little boxes are still triangles except on A) Why is triangle OBG ~ triangle OTE?

Answer 5

Redrawing here to make this easier

Answer 6

Right so for (a) would it be just because of dilation
?

Answer 7

You are right in that we have dilation, its actually just like the last two triangles we had.
I am just hesitant because it seems like a good point to want a sketch of a quick proof for that

Answer 8

Scetch?

Answer 9

ok this happened before
I think I just hit backspace and it messed everything up?

Answer 10

Its okay

Answer 11

anyways i was trying to say:
Why is OTE similar to OBG
welll...
<O = <O <-- these are the same angle
<T = <B and <E = <G <-- corresponding sides along transversal
so OTE is similar to OBG by AAA similarity postulate
this is the same proof as before, it just seems like a better justification for why than "dilation"
maybe its just me though, that question isn't quite clear what it wants

Answer 12

Okay, yeah that makes sense.
I dont know what the paper wants either. Its vague.

Answer 13

generally in high lvl maths i've done so far it is always put this way for a proof: "show that ..." "prove that ..."
and if you can't tell, do the proof anyways

Answer 14

but either way, that answers (a) sufficiently to me

Answer 15

Okay :)

Answer 16

now the fun part is finding all the side lengths they asked for, given the ones we know

the first thing we should do is probably put all the information onto the diagram to make it clear

Answer 17

Yay fuuun *sarcastic wooh*

Answer 18

this computer is being reluctant to highlight
mTOS = mSOE
TE = 6 cm
OT = 2 cm
OE = 5.8 cm
OG = 4.35 cm
AU = 0.45 cm


Agree with where I put everything? Hopefully it is in the right spot because there is a lot of room to misplace
