- Hey students, in this tutorials I have solved the part 3 of this question once again in much easier way using AA similarity criterion. You can still refer to following video to watch first 2 parts of this question. Though, it does include the 3rd part as well but now you have option to solve it in either way.
Example 8: In Fig. 6.33, CM and RN are respectively the medians of ∆ ABC and ∆ PQR. If ∆ ABC ~ ∆ PQR, prove that :
(i) ∆ AMC ~ ∆ PNR
(ii) CM/RN = AB/PQ
(iii) ∆ CMB ~ ∆ RNQ
In this tutorial, you will find the explanation of the following:

Exam ke depression me yeh music aur darata hai 😢😢
Sir, triangle ABC me CM median h toh angle MCB= angle MCA nhi ho skta kya...
Similarly, angle NRQ= angle NRP ho jayega
Or, angle C = angle R hai hi
Then, angle MCB = angle NRQ ho jayega
Phir, triangle CMB similar triangle RNQ ho jaayega.
Aisa ho skta h sir plz bata dijiye
Do you still have this query?
Yes sir
@@KumarRishu1819 I will respond tomorrow.
No. Median is not the angle bisector. It bisects the side. So these angles may not be equal. Try making different triangles with different lengths and draw medians. Either it will be quite obvious visually that medians are not angle bisectors or you can use protractor to check it. Let me know if you still have any doubt.
Sir chapter 10 (circles) example no. 3 can we solve that question by using trigonometry is it possible or not and why . Sir please take my doubt please sir🥲🥲
Sir to me aise kon kon se basic chapters padh lu ke me 7 aur 8 class cover kar lu please reply
I just replied to your previous message.
Sir me lockdown ke wajse class 7 aur 8 ke class attent nahi kiya hoon aur mene books bhi nahi le thi to mai ye dono class padh nahi paya hoon aur abb me class 9 me hoon aur mere se kuch nahi aaraha hai maths me
You need not worry about it. This is a very common problem among students. That is why I have put huge effort in making detailed conceptual videos. I would suggest you to have patience and watch especially the conceptual videos that I have created for every topic of every chapter. Go to www.mathemafia.com and start watching the TH-cam playlists that I have embedded for class 9. Let me know after studying the chapter 1. In case you face any issue, I will try to respond. Good luck!!!
