Geometry for anybody who knows it ~.~ thx

stranger2:

nevaehhh:

Ok, to start off, which one do you think it is ?

xxxFrancisco14xx:

m∠QST = 72°

stranger2:

\(\color{#0cbb34}{\text{Originally Posted by}}\) @nevaehhh Ok, to start off, which one do you think it is ? \(\color{#0cbb34}{\text{End of Quote}}\) I thought it was B

stranger2:

\(\color{#0cbb34}{\text{Originally Posted by}}\) @Hendrixapeals Stronger is bryana \(\color{#0cbb34}{\text{End of Quote}}\) ?

xxxFrancisco14xx:

Lemme explain, Given: m∠SQR = 108°, Quadrilateral SQRT has diagonals QT and SR that intersect at point U, We can tell that: m∠QST = 72°

xxxFrancisco14xx:

I think its really hard

stranger2:

\(\color{#0cbb34}{\text{Originally Posted by}}\) @xxxFrancisco14xx I think its really hard \(\color{#0cbb34}{\text{End of Quote}}\) which is why I asked the question

\(\color{#0cbb34}{\text{Originally Posted by}}\) @xxxFrancisco14xx Lemme explain, Given: m∠SQR = 108°, Quadrilateral SQRT has diagonals QT and SR that intersect at point U, We can tell that: m∠QST = 72° \(\color{#0cbb34}{\text{End of Quote}}\) 106° not 108°

xxxFrancisco14xx:

@jhonyy9 wym?

xxxFrancisco14xx:

The answer is m∠SQR = 108°

nevaehhh:

It's <RQS not SQR just fyi-

jhonyy9:

pls re-read the text

xxxFrancisco14xx:

okkokokokok

xxxFrancisco14xx:

was it a direct answer?

stranger2:

The dude is clearly copying from another site, and is copying the wrong thing please-

xxxFrancisco14xx:

m∠SQR = 108°

jhonyy9:

just 106°

Has your teacher talked about any theorems ?

stranger2:

yes but I dont rly understand them so..

nevaehhh:

Ok- that's fine I can explain the ones you need to solve this~

nevaehhh:

Alright in the choices, let's try to eliminate some...

nevaehhh:

I think we can eliminate B, doesn't that angle look a littleee too wide to be 53 degrees ? This isn't mathematic, but we can use observation~

nevaehhh:

\(\color{#0cbb34}{\text{Originally Posted by}}\) @nevaehhh I think we can eliminate B, doesn't that angle look a littleee too wide to be 53 degrees ? This isn't mathematic, but we can use observation~ \(\color{#0cbb34}{\text{End of Quote}}\) 74*

This isn't mathematic, but we can use observation~ \(\color{#0cbb34}{\text{End of Quote}}\) 74* \(\color{#0cbb34}{\text{End of Quote}}\) oh true, it is too wide so yes we can eliminate that

Hoodmemes:

\(\color{#0cbb34}{\text{Originally Posted by}}\) @xxxFrancisco14xx m∠QST = 72° \(\color{#0cbb34}{\text{End of Quote}}\) Might I ask how u got this answer?

nevaehhh:

\(\color{#0cbb34}{\text{Originally Posted by}}\) @Hoodmemes \(\color{#0cbb34}{\text{Originally Posted by}}\) @xxxFrancisco14xx m∠QST = 72° \(\color{#0cbb34}{\text{End of Quote}}\) Might I ask how u got this answer? \(\color{#0cbb34}{\text{End of Quote}}\) please wait until we're done, not trynna be rude~

jhonyy9:

what you know about parallelograms ? how are the opposite angles and sides ?

nevaehhh:

Ok... so now we have A, C and D...

nevaehhh:

Which one do you think it is ?

stranger2:

...maybe A irdk

nevaehhh:

I don't believe that's right but it's all good- now let's get into these theorems~

nevaehhh:

Alright... now look at this parallelogram. It looks like it's kinda "chopped in half" right ? Like someone put two exact triangles together, to make this shape... now since these triangles are "exact", what does this mean about their angles ?

stranger2:

equal or congurent right

nevaehhh:

Yep ! Since, the triangles are the same... their angles are congruent~

stranger2:

oh ya

nevaehhh:

Alright... so we already know that <STR=106... now look at it again, does that angle sit in a triangle ?

nevaehhh:

Is it "in" a triangle ?

stranger2:

no?

nevaehhh:

|dw:1611518619521:dw|

stranger2:

oh yes

stranger2:

I think-

nevaehhh:

That represents the angle- the angle is "in" that triangle... ok now remember what we said about the triangles being congruent ?

stranger2:

yes the triangles are congruent ...

nevaehhh:

|dw:1611518782096:dw|

nevaehhh:

Ok... now what is the name of that angle ? Look back at the problem rq~

nevaehhh:

We will discuss the theorem after you get it

stranger2:

so im supposed to be finding the name of that top angle right

nevaehhh:

\(\color{#0cbb34}{\text{Originally Posted by}}\) @stranger2 so im supposed to be finding the name of that top angle right \(\color{#0cbb34}{\text{End of Quote}}\) Yes ma'am

nevaehhh:

|dw:1611518956994:dw|

stranger2:

SQR or RQS I think

nevaehhh:

Good job ! RQS=106~

stranger2:

thx so wut else ..

nevaehhh:

Now... time for theorems aka proofs

stranger2:

yes...

nevaehhh:

All you really need to know is that when two angles are across from each other aka alternate, then they are congruent- lemme draw an example rq~

stranger2:

ohhh and ok I'll wait

nevaehhh:

|dw:1611519183929:dw|

stranger2:

yes

nevaehhh:

|dw:1611519287722:dw|

stranger2:

so there opposite exterior angles bcccccccc there on the opposite side and on the outside right?

nevaehhh:

|dw:1611519526882:dw|

stranger2:

so,

nevaehhh:

when the angles are opposite, they are equal

stranger2:

I see

nevaehhh:

1=8 and 2=7, shows Alternate EXTERIOR theorem, and 3=6 and 4=5 is the Alternate INTERIOR theorem.

stranger2:

oh ya, I get that.

nevaehhh:

do you need any more help with anything ? did i help ?

stranger2:

Yes you really helped a lot thank you so much <3 so wait was that it

nevaehhh:

yeppp- that's all

nevaehhh:

and you're welcome<3<3

stranger2:

I might post another one. if u hav time can u help.

nevaehhh:

absolutely ~
