[@omnarayanpandey919]

2:36:12 doubt! How OC=OE when O is not the centre. The explanation is wrong i guess.

[@srilalithavlogs7323]

1:04:43 It can be proved congruent by SAS because angles opposite to equal sides are equal, Since OA=OB Angle OAD=Angle OBD

[@somyaarora4194]

Ma'am do we need to learn these theorems if we have to use it in question

1:53:48 mam in this is writing reason in words important , instead of that can we mention the no of theorem ( Eg : theorem 5 )

[@Love.you.always.cutie...]

Doubt:- So mam in the Theorm number 2 where the perpendicular from the center of a circle to a chord bisects the chord I have a doubt. So, what if the line OD doesn't form 90 degree angle with AD or DB? Does this theorm work over there too?Please explain my doubt soon and I'll be waiting and your teaching is very excellent mam Thank you mam

[@Catch_Gaming2010]

Mam in converse theorem 1 you said that angle 1=angle 2 by v.o.a but in ncert book the figure is not given as such type that you have made in the class so what reason we have to apply on it. Thanks

[@nazmim4854]

2:37:55 in this question can't the triangles be alternative interior angles ?

[@prempremyadav9032]

In that one question where all three angles were 60 in Thant question by alt. Int. Angle there angle we have to find that will directly be 60 right ??

[@jaskiratkaur7361]

Ma'am you did a mistake in theorem 1 and 2 , the angles are not vertically opposite ... vertically opposite angles are formed only when the lines are straight . In the diagram the lines are not straight ( not diameter ) .

[@chotachatri2910]
