00:00Hi friends, how are you all? I hope that you will be very big in this video lecture.
00:16We are going to talk about the 9th class of chapter circle.
00:21And this question comes along with different books and languages.
00:25We are going to talk about the same thing as the whole thing.
00:36You can see all of these other books.
00:37We are going to talk about the most important books on this video lecture.
00:41For the place?
00:50It's angle B measurement is angle B measurement that is equal to half the difference of these two angles
00:59In both angles of difference between half and half
01:02Which angle?
01:03This angle
01:04Let's start
01:05Let's start
01:06Let's start
01:07Let's start
01:08What are we going to do?
01:09We are going to join this point E to join this point E to join this point
01:15This point E to join this point
01:17So what do we do?
01:22What are we going to do?
01:24Let's start this point
01:26Let's start this point
01:27How much angle is an angle from the center?
01:29How much angle is it?
01:31What is the angle?
01:33Is the angle around the rest of the circle is?
01:35It's a angle A or C
01:39A.O.C.
01:41AOC which is figure?
01:42AOC,
01:44which is this angle.
01:46Now,
01:47make it to me?
01:49This angle is which one is which one is called this angle.
01:55Clear?
01:56So angle AOC which one is called this angle?
02:00This one is called this arc.
02:02This arc is called this arc.
02:04In the two joining,
02:05this arc is called the rest of the circle.
02:08of the circle, this is the rest of the circle. When we talk in the arch of context, the rest
02:14of the circle is the rest part of the circle. This is the rest of the circle, which means
02:19this is the two points, and the add points to the end. This means the angle which we
02:26have showed from red colours. This angle rest of the circle is the root of the circle,
02:32This angle is due to this angle and the angle is due to this angle by this angle.
02:39This angle is due to this angle.
02:42Let's try it out.
02:44We will write this direction.
02:46We will write this direction.
02:51We know that by an angle by an angle the angle is subtended by
03:01at the circle is double the angle subtended by it in the rest part of the circle, rest
03:25part of the circle. So, this arc center of the circle is double the angle of the circle.
03:36So, this arc center of the circle is aoc, so therefore angle Aoc must be equal to double
03:42of angle 1. Now, what do I do? Let us do this two. So, now we can do this angle 1 equal
03:48to by two division. So, 1 upon 2 angle Aoc can be written. This is very important point
03:54to say that we have a question number 1. So, angle 1 equal to what? Angle 1 equal to half
04:00angle Aoc, so we start with this angle. So, we will start with this angle. But here
04:04we have to write D O E. And D O E, see this angle angle. And this angle is called
04:11which angle is called. So, we will say this angle is called D, which we have started with
04:16the green colour. So, this arc is called center of the circle and this arc is called
04:23of the circle. And this angle is called D O E. And this arc is called D O E. And this
04:27so
04:29so
04:31if
04:33you
04:35are
04:37the
04:39angle
04:41about
04:43the
04:45angle
04:47and
04:49angle
04:51is
04:53same
04:55reason
04:56So this implies angle 2 is what happened to the angle?
05:02Half angle D O E to the same thing.
05:07And you can say equation number 2.
05:10I think things are understood here.
05:12It's easy to do this.
05:14Just give it a little bit.
05:16Now let's see.
05:17This is a very important point.
05:18If we look at this thing,
05:20then tell us what is it.
05:22It's represented by black color.
05:25So we have a triangle.
05:27It's called triangle P A E.
05:30And if we add this side to the other side,
05:33then it's produced in this side.
05:35And it's produced in this side.
05:37And it's produced in the other side.
05:39It's called angle 1.
05:41It's called 1.
05:42What is this triangle?
05:44It's the exterior angle.
05:46And if it's the exterior angle of this angle,
05:49then what is the measurement?
05:51By two opposite interior angles.
05:54So now in triangle P A E.
06:04What can we say?
06:05Angle 1.
06:06Which one?
06:07Sum of two opposite interior angles.
06:10Angle B plus angle 2.
06:13What the triangle?
06:14To go above the exterior angle isror.
06:15To go above and do it.
06:16Now B.
06:17As B.
06:18As B.
06:19As B.
06:20As B.
06:21As B.
06:22As B.
06:23As B.
06:24As B.
06:25As B.
06:26As A B.
06:27Minus angle 2.
06:28Lick सकते है ऐसा.
06:29Angle 1 की जगे पर angle 1 की value रख दो.
06:32So, this equal to half angle AOC.
06:36Minus angle 2 की जगे पर क्या रख सकते हैं?
06:39Isकी जगे पर रख सकते हैं?
06:40Half angle DOE.
06:42Half क्या गर ये common में लीजिये?
06:44So, यहाँ से बचा AOC.
06:46और यहाँ से बच गया angle DOE.
06:50So, angle B equal to half the difference of these two angles.
06:56और यही चीज़ देखो हम लोगो को शूब करनी थी.
06:59दो मिट करता हूँ कि आप लोगो को solution समझाया होगा, परसंदाया होगा.
07:03अगर ऐसा है तो गीटे को like के साथ में high bigger day.
