Prove: Angle Bisector Theorem

[@wetsuitcandy]

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

It is about similar triangle properties

[@chocolate_blue8798]

AD/ED = DB/DC = AB/EC

Beautifully explained sir thank you

[@dancingbaba9076]

Wow great sir, the way u taught will remain in brain 4 ever , thank u very much

Nice From India 🇮🇳🇮🇳🇮🇳🇮🇳

[@touhami3472]

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?

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

[@aneeshsheesh5843]

Yes

[@ktrinaningthoujam6677]

Sir , you're Korean .

[@Ajey_Sah]

Are you from India sir ? ❤️

[@shwe746]

Didn't you notice by his way of speaking bro.

[@michellauzon4640]

It's immediate with law of sines, using BAD = DAC and sin(BDA) = sin(ADC).

[@ps-mx2dq]

You can also prove this by using basic proportional theorem

[@bvnayak6952]

Very Bad Proof..... Not Justified

[@mentor6059]

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.

[@pola_behr]

lmao yes it is

[@Ibrahim_Ezzeddine.]

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.
