Magnet Brains can you pleassse make a playlist of Class 6 Maths NCERT Exemplar, I really need it 😕😕😕

[uditjain]

Sir in MCQ in question no 5 it is an isosceles triangle so it is 55 and 55 degree

[gaddilamborghini]

Thank's sir this is very helpful in lockdown ❣️❣️❣️❣️

[tejpalyadav]

Sir please ch.13 maths exoptnents and powers

[mishra._.x]

Heads off to them who watch this full video 😚

[AditiSingh-wgqg]

Thank you so much sir you cleared my all doubts of this chapter

[preetigupta]

is again incorrect it should be option d) bcs the difference of two sides is not greater than the third side

[raghavrollnumber]

sir question 7 should be c) right angled triangle according to pythagoras in it we can take 5 as hypotenuse and 3 & 4 as arms so the 3^+4^=(9+16) 25 and 5^ = 25

[preetigupta]

Sir question 7 is wrong bcs it should be right angled triangle bcs when we use converse Pythagoras then 3²+4²=5²
=9+16=25 hence ot should be right angled triangle
Thanks for reading my message

[raghavrollnumber]

Sir according to me question 18 me c) right_ _ _ _ equilateral is wrong and d) difference _ _ _ _ _ _ _ side is the correct answer

[priyadarshinirout]

Sir 18 should be d Sir. But thank u so so much sir.. But 18 is d

[neelambhoir]

I am so glad i watched your video at the end and i got 19/20🥳

[preetigupta]

No ways again incorrect
Here, 7+9=16 so it shall be less than 16
Next 9-7=2
So the answer should be c) between 3cm and 16cm
Or less than 16cm but more than 2cm
4th question u got wrong sir I pointed all of them out

[preetigupta]

Q13 is also wrong sir here we again need to use Pythagoras theorem
So here let's take the base as 4m and the perpendicular as 7-4=3
Then, 3²[perpendicular]+4²[base]=h²
9+16=25
25 square root=5
Hence 5 is the answer
Sir u can check it by making a triangle
Actually u needed to made the line from the 4m Long tree to the 7m long tree but sir u drew a line from the 4m ling tree to the 7m long tree, it means that it was not its rop it reached onlt its 4m hieght not 7m, u needed to make a hypotenuse
Thanks for reading my message [answer 5]
