Beautifully explained sir thank you
Wow great sir, the way u taught will remain in brain 4 ever , thank u very much
Angke BAD=DAC (bissector) (1)
In triangle BAD:
SinBAD/x =sin(BDA)/a (2)
In triangle DAC:
Sin(DAC)/y=sin(ADC)/b
=sin(BDA) (3) :ADC=pi-BDA.
(1), (2) and (3) give: x/a=y/b.
why tf would you use trig in an easy problem?
@@lolerishype to solve it !
Nice From India 🇮🇳🇮🇳🇮🇳🇮🇳
Amazing conclusion
3:28 I got lost here, so just so no one else does, angle CAD is equal to CED because it's also equal to BAD! That's the theorem itself, the bisector of angle CAB makes CAD = BAD
😢
Superb explained in less time🤗🤗🤩

Thank you! The proof was very clear. Btw, are you from S. Korea?
yeh
It’s Japan probably

For me proof using law of sines is clear
yeh
this problem is intended for geo 1 students (Grades 5-8).
@@lolerishype so but what is your problem here?
Thank You
nice
Nice
very sexy proof. extremely justified
Thanks
thanks sir
Super
Your accent! 😍
ARE YOU DREAMING?
You can also prove this by using basic proportional theorem
Sir , you're Korean .
Are you from India sir ? ❤️
Didn't you notice by his way of speaking bro.

Can you prove the length of AD is equal to sqrt(a*b-x*y)?
Yes

Found a pajeet
It's immediate with law of sines, using BAD = DAC and sin(BDA) = sin(ADC).
Usin theorem Talis
Eh
Very Bad Proof..... Not Justified
To me it is pretty goog! There are different ways to proof the math formula. You have to choose one of the ways you like.
lmao yes it is
I know it was like someone was on drugs the most stupid prove I have seen in my life even I tried it and do not make sense at all.
