Hello ma'am,I am big fan of your vidoes and i have watched all your 9 th grade math videos.While explaining theorem 9.5, we should consider the perpendicular distance from the center and not the distance from the centre point to the chord (radius) .In the example given AB =DC if only OX=OY(perpendiculars ) .
If i am wrong ...sorry ma'am
Mam please prove theorem also in a separate video
Best of luck guys for tomorrow exam 😊
Best teaching
Thank you mam yu are best teacher I'm studying from you from 6 class ❤❤ thank you mam

Mam pls gravitation chapter aapne approx maths ka syllabus toh complete kr va diya h but what about science ?
21:31 sorry to be that guy but the theorem is actually based on the hemisphere of the circle rather than it's semi-circle
It has been improvised as a 3rd dimensional figure in the theorem
Very nice explenation mam ❤
