In this video, let's discuss the interior angle biosecure theorem.
All right, over here, we have Triangle Pedic.
You all right?
Now I have an angle over here.
This is Angle Petechial.
Now, let me draw the angle by sector of this angle over here.
Let the angle by sector be D.F..
Right.
So angle one is equal to angle two because we have constructed the angle by sector now as per the interior
angle biosecure theorem bitterly divided by dequeue.
That's the two sides of the angle which was bisected.
The ratio of these two sides will be equal to the ratio of BSF by RFQ.
Let me that over here.
Prebuy dequeue is equal to EPF by RFQ.
Now remember, when you take the order, the order is important.
You have taken beauty as the numerator and dequeue as the denominator.
Right?
So in the numerator over here you need to take the side which is closer to this side.
So BFC should be the numerator and if you should be the denominator.
So if you write it as if.
Q By both, that would be wrong.
Right, because you have taken it as prebiotic.
Q Similarly, let's take one more case.
You have an angle over here.
Say this is the angle by sector, right.
Let's write this as X, Y and E and B, what does this theorem say.
It's divided by Y will be equal to a baby or B by its will be equal to a baby.
Right.
Because you've taken X over here, the numerator, so you need to put it, which is closer to X in the
numerator.
And this is what the interior angle bisecting theorem says.
