Find equation of the angle bisectors of a pair of line Challenge Question

[@musasjawo2044]

Thanks but sir can you chech your first equation I hope it should be -3(7x-9y+10) instead

[@MathematicsTutor]

Yes, that is right. Thanks

[@AbhishekKumar-pz5nd]

Yes u are right

[@rehamfaheem3770]

I dont why why this video seems sooo satisfying 😁😌

[@HeyGuys-w4q]

what about, x+y-2=0 and 2x-3=0?

[@marvinobillo319]

Kindly check the 3(7x-9y+30)=0 sir

[@Gocchin]

thank you for this video, I understand it now.

[@MathematicsTutor]

Thanks for sharing and All the Best!

Thanks prof you are just a wonderful person

Welcome

[@DavidGoggins-w6y]

Thank you sir

[@maicee7603]

how to know which line that divides the small angle and which line that divides the bigger angle?

[@ranjanabhangade501]

sir you first eqn is wrong

[@mashupofvikas1297]

The equation of the bisector of an angle between the lines x-y+2=0 , 7x+y+1=0
Sir I am not getting this problem can u please explain

[@MathematicsTutor]

Check this video: ruclips.net/video/MGM4CUPlTA0/видео.html
If you don't get let me know what you don't get. Then I will try to help. Thanks

[@mashupofvikas1297]

For the 1st equation denominator is√2 and for 2nd equation denominator is √50

[@mashupofvikas1297]

After I am not getting sir

[@abhassharma7033]

sir why didnt u apply +- on L.H.S after opening the modulus??

[@salukaranapura6031]

Because you get the same equations . No matter you put +-, so one side is enough to get the equation

1 Find the equation of bisector of line x+2y+3=0 and 2x+3y+5=0.

[@MathematicsTutor]

Follow the method described in the video to get the solution. Thanks

[@Harsh-zj7lm]

which is acute? you missed the most important point

[@MathematicsTutor]

Thanks. The question was to find the equation of angle bisector. Both the equations are provided.
Yes, It can be taken as part 2 of the solution to find which is acute angle bisector. Appreciate your feedback. Thanks

[@Harsh-zj7lm]

Sorry to bother you, i just found the other video. Thanks

[@MathematicsTutor]

Here is one for obtuse angle: ruclips.net/video/MGM4CUPlTA0/видео.html

[@engrRGV]

Anil Kumar how do we know which one is for acute

[@MathematicsTutor]

Thanks for the question. Here is the link for the video to find obtuse angle bisector. You can get the acute angle condition also. Hope that helps.ruclips.net/video/MGM4CUPlTA0/видео.html

[@Avighna]

One of the final answers is incorrect.
The lines are:
- 7x - 9y + 10 = 0
- 99x + 77y - 100 = 0

[@fuscabloangelo9511]

Sir why there is ± sign instead of a positive sign?
I mean why the left side of the equation comes up to be positive and the right side has two signs(±)

[@dhirajjadhav2022]

|x| = |y| --> x = (+ or - )y
Because we don't know the about the signs of x and y

[@romanempirereigns8100]

For any homogeneous curve of form ax²+2hxy+by², equation of pair of angle bisector is [(x² - y²)/(a-b)]=(xy)/h

[@holyshit922]

If we follow steps of construction we can get a method for finding equation of angle bisectors
1. Solve the system of equations
3x+4y=5
12x+5y=7
to get coordinates of intersection point and call if point A
Choose the point on the line 3x+4x=5 (f.e. B = (3,-1) )
Calculate distance from A to B
Write equation of the circle with center at A and radius AB
Solve the system of equations
(x-xA)^2+(y-yA)^2=|AB|^2
12x+5y=7
to get two points Ck (k=1 and k=2)
For each point Ck do the following
Write equation for the line through the points Ck and B
Write equation for the line perpendicular to the line CkB through the point A

[@philipbangura7489]

If we divide the first equation by negative 3, the answer will be 7x-9y+10=0.

[@yevsell]

I applied it to normal vector equations and it worked....Thanks alot!!

[@vitocipponeri6773]

could you type out how you did that please?

You are good. God bless you
