Sir you are great... your teaching is
So beautiful
So Elegant
Just understanding like Wow...😅😅❤❤

[rollerdept]

You are best teacher in the world sir😃👨‍🏫

Sir if chord is equal to the radius then triangle formed will be equilateral triangle hence o =m =n = 60°
(Ex.no. 2)

[kartikbhosale]

THANK YOU SO MUCH SIR DADA BHAIYA 🥰🙏🏻❤️🌍

[dr.bhangep.b.]

Hii sir!!!!
2nd question ko hum bahot easy bana sakte hai
Since chord=radius, us triangle ke all sides equal honge
To wo ek equilateral triangle ho jayega
Aur equilateral triangle ka har ek angle 60 degrees hota hai
So theta hame directly mil




Thank u sir for such great lectures without any cost❤❤❤❤❤❤

[khushipatel]

Rahul sir your teaching is very nice😊😊

10:54 simple tip: all the sides are equal I.e. 9 therefore it's a equilateral triangle so according to the property of measurement of equilateral triangle= 60°, no need to solve this much

Thank you soooo much sir for your support

When an arc of a circle cuts off a chord of length equal to the radius, it forms an equilateral triangle with the center of the circle. In an equilateral triangle, all sides are of equal length.

So, if the radius of the circle is \(9\) cm and it forms an equilateral triangle, then the length of the chord would also be \(9\) cm.

Now, to find the length of the arc, we can use the formula for the circumference of a circle and scale it down to the proportion of the angle formed by the arc:

\[ \text{Arc Length} = \times 2\pi r \]

Since the angle formed by the arc is \(60^\circ\) (as an equilateral triangle has all angles of \(60^\circ\)), we can calculate the arc length:

\[ \text{Arc Length} = \frac{60}{360} \times 2\pi \times 9 \]

\[ \text{Arc Length} = \frac{1}{6} \times 18\pi \]

\[ \text{Arc Length} = 3\pi \]

So, the length of the arc is \(3\pi\) cm.

Thank you so much sir 🙏 your teaching super😊

[ShubhadaKAMBLE]

sir apne 5π/12 ki jagah 5π/3 likh diya uske wajah se apka answer r1/r2=5/4 ki wajah r1/r2=5/1 aa gaya

[prathameshraut]

Love you sir very very thank you sir all concepts are clear

[SohamJadhav-nm]

Sir bohot excellent lecture hai mujhe kabhi maths solve karne mei itna maza nhi aaya jabse aap dikhana shuru, thank you so much sir u make maths simpler than ever❤
