Friends,
This is a Math video. This is our nineteenth webisode (WB-19) on "Series 10 - Circles".
In this video, we learn that if a line segment subtends equal angles at any other (randomly chosen) two points, then all the four points - i.e. the two end points of the line segment and the two other (randomly chosen) points - are concyclice i.e. all these four points lie on the same circle. Then we prove this theorem.
This video is suited for class-9 (Class-IX) or grade-9 kids.
Cheers,
Friends at Rising Pearl

Thanks so much
Hi, you are very welcome! Cheers,
Sir I have a doubt how can we make circle when the center is not given to us.Plz answer asap.
Draw two cord and draw their perpendecular bisector then the line perpendecular bisector meet at a point this point will be centre
Time taking but concept clearing 😎😎

What do we call this theorem?
I mean.. Simple Name of this Theorem..
Nice
Welcome, cheers
What is the abbreviated reason associated with this lemma (that one would put in brackets)?
sir why can't u be our teacher in the school for maths really it's awesome teaching all my doubts are cleared especially geometry
Hi Satish,
You are awesome! Thank you for those kind words. I appreciate it. I am just glad that you and others enjoy watching these videos and are learning from them.
Cheers,
please prove that quadrilateral formed by internal bisectors of quadrilateral is cylic and you teach very good..............
I understood this theorem very well
Good
Hello, i must say, this video us fantastic, but i have a question : can we also prove this by saying these 4 points are cyclic quadrilateral?
Hi Ahmed,
Thank you very much. I am glad that you liked the video and found it helpful. Please check out some of the other videos as you find them helpful too! Regarding your question, please elaborate that more. I am not sure how what you are asking is different from what is explained in the video. If you can rephrase/elaborate the question, that will help.
Cheers,
can we call this that the theorem is related to cyclic quadrilateral
Hi Satish,
Cyclic quadrilateral means such a quadrilateral whose all four vertices lie on the same circle. From that standpoint, yes you can say this theorem is related to cyclic quadrilateral.
Cheers,
Sir please tell can we take points c d any where on the plane
Hi Nagalatha - Thanks for your question. Yes, C and D can be any 2 points on the plane. However, there are only 2 conditions. First, both C and D should be on the same side of line-segment AB. Second, ∠ACB = ∠ADB. Hope it helps! Cheers,
sir which software you used for making webisode
Thank you sir
Thanx bro
You are fantastic in explaining but you lack in the quality of video i can't see what's typed.
