Arcs and Central Angles - YourTeacher.com - Geometry Help

[NabbyDudeX3]

I just want to let you know that you`re my hero.

[jennylicious1996]

That's our lesson in math earlier.

[ivantot017]

wer the fuck 180 cme from?? plz

[ttham11223344]

@ivantot017 The perfect triangle must have 180 degrees in total

[IvanderHaisley]

@ttham11223344 its not "perfect" ... a triangle must have a sum of all internal angle equivalent to 180º

[ttham11223344]

@IvanderHaisley But only a perfectly accurate triangle can have accurate angles. I see what you mean. I didn't mean as in the perfect triangle but a perfectly drawn triangle.

[IvanderHaisley]

@ttham11223344 oh yeah .. i get it .. you mean to say an accurate triangle that being illustrated ... i have one of those problem too -_- . like an inscribed angle on a circle having an angle measuring "50º" and when i got a protractor it measured 85 º /.. definitely inaccurate :D

[AutumnxDay]

I liked the circle help with the algebra is so slow.. x + x is 2x... ;O WOW.. so hard.. >.>

DEAR ALL SCHOOL PRINCIPLES, PLEASE FIRE EVERY SINGLE TEACHER AT SCHOOL! & Hire Youtube and Google. (; I think all us students can agree we learn MORE FROM THEM than we do from the teachers at school that can barely teach. Isn't is sad enough that we have to go ONLINE to find help instead of the place we get our education from? YOUTUBE AND GOOGLE teach me more than school does! Sincerely, pissed off students.

[1355atlantis]

[TharwatAlshoufi]

Nice lesson by nice teacher

Tharwat

[Byaaaaaaaaaaaaaaaaa]

she has nice handwriting.

[smellmyclock]

my teacher is a piece of shit

[SlaminBamin]

Or you could have subtracted 50 from 180 and divided 130 to give you 65 :)

[patriciamarylaine08]

OMFG where have you been for all my life! THANK YOU ! i find it simple now !

[tereypil]

@jld181813: fact!



[jld181818]

She looks so happy at the end.

[rastagoon]

[LASSJ4]

[myb7ls]

[werethemfat]

She's a beast!

[samma1009]

SPEAK WITH EMOTION!

[ABCba5tard]

she needs to stop starring at the cam for like 5secs in the beginnig and ending

[lakeheadca]

Great lecture

[jbdancer1995]

I wish she was my teacher too. Her voice is a little monotonous but she explains it very clearly whereas my algebra teacher uses too many shortcuts where I don't know how he got those numbers. Her writing is a lot better than my teacher also.

[kingofdice66]

@jbdancer1995 i think you are full of bullshit, check patrikJMT of khanacademy, those are a looooooooooooooooooooooooooooo­ooooooooooooooooooooot better and you find everything you need

[yosuppdude]

I wish she was my maths teacher...!

[SpencerDrew08]

This is great, since I'm more of a visual learner, this really helps.

[Ps3capt]

THANK YOU SO MUCH

[UnknownHyperbowl]

IRISH ACCENT!!!!!!!!!!

[D4N3YCAHODA]

teachers are boring. i learn better with this videos.

[sarangjogi]

i dont know why but i wish u could be my substitute

[TooManyUnspokenWords]

She sound stoo robot-like, thats just the problem. But this did help my little brother hahah :]

[jerellojello15]

awesome mrs. lady just awesome

[Firebug538]

x.x I'm on the same page as HelloTrini haha.

Sophomore and I have NO IDEA how to do this stuff. However this makes a little more sense.

[IntentioalTroll]

Great video, too bad its nothing more than stupid ad for your site. People come on here looking for help, and all they can find is spam. Fuck you

[lateraligator2]

um, not even. it has 15 seconds of advertising at the start, but the rest is really helpful.

[cristel1445]

wow...this lesson was so difficult for me...but now, i am finding it so easy...and it's all because of you...thank you very much...you are really a great help...

[MegaFootballlover]

lol i like alwayzzz crack up at the end of these video..... first they sound like robots... then at the end there creepy smiles with the weired pause.. ...lol buh theses video help a lot.... no joke...hehe

[fashionista0914]

LOL, same here, she always smiles at the end.

[123lar]

im in 8th grade. i find this so hard.. thanks for helping me i have a geometry test 2morrow

[HelloTrini]

Omfg. I'm a sophomore in highschool and I'm learning this. And ur in 8TH GRADE??? OMFG. I feel so STUPID. DX

[AvPfan546]

lolz im in geomery my freshmen year =]

[jamesfirst92]

wait waaaaaaaa

why did that angle become 50 degree again ??

can someone explain it more simpler way

[HelloTrini]

Uhm.. Since that's arc is 50 degrees, the inside angle is 50 degrees also. I don't know why but it just is!! xD And since it's a straight line, all u do is subtract 50 from 180 (180 = straight line) and you get 130. Since there are 2 angles, just divide it by 2 and u get 65. There's no reason for that equation she pulled out...

[520nacy]

hahaha that wuz fuckin funny

[jordantoon]

uhhhhhhhhhhhhhhhhhh can you say it really slowly i didnt get wat the whole video said HAHAHAHHAHAHA

[88graves]

There's that creepy smile again at the end of the vid. Must be some sort patent or signature kind of thing she does to mark her work.

[RahmanMotors]

So true bro lmao

[bendeplata]

hmmm

[shyru32]

To 300 Music, the sum of the all angles interns of a triangle are 180 degrees

[300MUSIC]

where did 180 come from?

[skedoosh]

are you serious?

[300MUSIC]

im taking pre ap geometry next year buddy, i dont know this stuff yet

[mybestbuddies921]

The 180 came from the sum of the angles of the triangle.

[banana8shake]

you're allowed to at your school? you can be in geometry at grade 4? and take algebra 2 in 5th? DAMN. is it some school for the super geniuses?

[CaseAub12]

lmao or china?

[appleman1324]

lol i bet they learn the basics lol, you either learn this shit in 9 or 10th grade no matter what

[Bloodstride]

nerdddd

[KraziAzian]
