I graduated years ago, and recently realized just how much I miss looking at a Jumble of Shapes and proving that 2 triangles in it are the same or whatever (something something the comfort of finding order in chaos). But I pretty much forgot everything and didn't know where to start (and can't afford to pay for a course). My friend recommended Khan Academy and I cannot understate how perfect a recommendation that was! Your explanations are so clear, your use of color is helpful and almost festive, and even your tone is friendly, like you genuinely want everyone watching to succeed and believe that they can. And you're right- under all the years of rust from disuse, I finally feel my brain stirring as your explanations click neatly into place. I hope you know how kind and how important your work is!
4:10, this is proven by using Euclides postulate 5 (parallel lines). Interior angles add up to 180 degrees if the lines are parallel, and the exterior angle plus the adjacent interior angle add up to 180 degrees also.
in a 45min class i couldnt learn ONE thing from my math teacher and this time i WAS ACTUALLY PAYING ATTENTION !! (theres a first time for everything) but when i watch a 7min video i feel like a GENIUS
I've always hated maths in school. I just started learning in now when I'm 31 years old. It now makes sense. It was hard to learn maths in language that is not venec as a child
What you say at 4:10 is false...there is a proof that alternate interior angles when parallel lines are intersected by a transversal, which is then used to prove corresponding angles congruent.
@Lyric Yeager i had my teacher help me and now the video helps out to it was just not knowing that caused it to be like that then once my teacher showed a example the video helps just never edited the comments
you taught somethig to me in like a few minutes that my math teacher took 20 lessons to explain
ballistic_daksh lmfao
My math teacher linked this video to me. So would it be my math teacher teaching me, or this guy on this video?
Lmao
Oml😂😂🤣
Lol
it’s 11:28 pm i’m about to fall asleep and this video is my savior
@Evelyn Hernandez same
@Evelyn Hernandez well its hu tao now
11:15 🤣
SAME
bro you cannot imagine how much of a lifesaver this channel is
This is almost like cheating cause it's so easy to follow him in this video! Helps a lot for Grade 8 math.
Zaafir Ahmad lol
im doing this in grade 8
Zaafir Ahmad im doin dis in grade 7
hows grade 11 zaafir??
not bad, looking back at this comment makes me cringe hard haha
extra help: it all equals up to 180 degrees. so like 180-a = b
candy-kat! kitty-lichious! Linear pair right
this academy is great it helps me soo much with all the work I'm doing right now in Geometry Thank God for The Khan Academy!!!!!!
Be my math teacher
No mine
Bieng honest yup

s4r
4:11 now I'm not gonna actually write proof, just say everything is "intuitively obvious" XD
Oh nice 😂
Except that there is a proof for this Book 1, propositions 27-29 in Euclid's Elements
You are better then any math teacher all math teachers is not good
urghhhh watching this video because of geometry homework
Jaedo Oh oh my god same
Jaedo Oh me too
same
same just 5 years after u
Same
How come the only good teachers are online
What is the difference between transversal lines and transversal angles? Or are they the same meaning?
once again!!! thank you khan academy.
In Ethiopia you learn this in grade 6 this chapter was so difficult for me .thanks you helped me a lot. I wish you were my teacher
in pakistan we learn this in grade 6 too
Then how am I learning this is in america at 6th grade!?
I dunno but i hate it

He writes perfectly with a mouse :O

he uses a wacom tablet
He’s using a pen and tablet not a computer and mouse.
what app r u using for the drawing thing
I wish all school math teachers were from Khan academy
Thank you, you made it easy to understand :D
I watch this video cuse the teacher is putting it in our daily revision for new or old.......things that we will learn......
Thanks man this really helps a lot certainly better than getting a tutor
i love your simplicity

@@harigopaladamus9481 no
The way you say E is soothing asf
Thank you this was so helpful, you taught it better than my teacher,
This sort of helped me understand it better. But I am horrible at math so nothing can make me better
What application are u using please tell
How can you prove same-side exteriors ?
Bruh I didn’t even know that was a thing😭
Thank you Rashid Khan
4:10 we can prove that with test of similarities of triangles
I've always hated maths in school. I just started learning in now when I'm 31 years old. It now makes sense. It was hard to learn maths in language that is not venec as a child
Just warming up for exams
This did help me though. So thx:)
Love your Videos!

Ok ok woah this was too much for my brain to handle

Do I Like This? No. Do I Have To Watch It For Math? Yes.. xc
I never understand this guy he sounds like a fish
Watching this because teacher made me.
You searched this up or got it for homework
Yeah.
No
Thank you so muchhh
can you please say the place you draw
KHAN ACADEMY IS A GOOD EXAMPLE OF ARABS
