Mst explanation 🎉❤
1 st class teaching
You may join narayana school you may get a high package of 2-3lakhs
❤❤
Good explaining
I guesss instead of proving them congruent you could have just drawn the remaining side and hence by diagonal bisector property of a parallelogram they both had became already congruent. Btw good explanation.
Mam be given that ad is meadian of a triangle ABC but ad is a median not a perpendicular then why how can we write that BD is equal to DC
Look beta, median is something that divides the given line into halves and perpendicular is just the height of the given figure. Also perpendicular bisector is the straight perpendicular line that divides or bisects the line into two halves and as well as is a height to the given figure. I am just a random teacher but hope this helps.
Thanks a lot di for extremely easy solution ❤❤❤
Super mam continue this🎉

Others😌-> nice explanation Me🙋♀-> ma'am is lefty
MAM IN LAST STEP CAN'T WE SIMPLY THE ROOT?
Since p is divisible by 5 P is a multiple of 5 So 5 needs a number to multiply with so that it can give p So 5C means 5×C where C is the other number. I hope this helps..
It is more important for us ma,am because we are 10th 😊❤
