00:00:00,600 --> 00:00:04,620
In this video, let's discuss angle by sectors of a triangle.

2
00:00:05,040 --> 00:00:06,910
All right, let's take an example.

3
00:00:07,080 --> 00:00:09,190
We have a triangle, ABC over here.

4
00:00:09,480 --> 00:00:13,330
Now, let's construct the angle by sector of Angle ABC.

5
00:00:14,040 --> 00:00:14,510
All right.

6
00:00:14,520 --> 00:00:22,410
So this is the angle by sector of angle B, that means if this point is all, then angle A, B or is

7
00:00:22,410 --> 00:00:30,030
equal to angle CBO right now, let me draw the angle by sector through C and let me draw the angle by

8
00:00:30,030 --> 00:00:31,060
sector through it.

9
00:00:31,560 --> 00:00:35,640
Now you will see that the three angle bicyclers intersect at the point.

10
00:00:36,840 --> 00:00:39,120
And we call that point the center.

11
00:00:40,350 --> 00:00:48,200
All right, now with the center as the center, you're able to draw a circle that is inscribed inside

12
00:00:48,210 --> 00:00:49,380
triangle ABC.

13
00:00:50,880 --> 00:00:58,440
And this circle is called the Inner Circle of Triangle ABC, you can note that each side of triangle

14
00:00:58,440 --> 00:01:05,880
ABC, Art and dance to this circle to over here side ABC is a tangent to the circle.

15
00:01:05,880 --> 00:01:08,730
You can see it's meeting the circle only in one point.

16
00:01:09,030 --> 00:01:15,600
Similarly, site is a tangent to the circle and side is a tangent to this circle.
