In this video, let's make an interesting observation.
We have seen that if you have a right angle triangle and the sides are B, C and then B Square is equal
to A squared plus C square, where B is the hypotenuse, which is the side opposite the right angle.
All right.
Now let's take an acute angle triangle.
Remember, an acute angle triangle is a triangle where every angle is an acute angle.
All right.
Over here, the sides of this triangle triangle is A, B and C, and you will find that B Square is
less than A squared plus C square.
Let's compare that with the relation over here.
Over here.
B Square is equal to a square square over here.
B squared will be less than is square square.
All right.
Now let's take an obtuse angle triangle.
Besides A, B and C and B is the greatest site over here, and you will find that the greatest site
is the site opposite the greatest angle or the site opposite the obtuse angle.
This angle will be an obtuse angle.
The side opposite the obtuse angle will be the greatest site.
Now, in this obtuse angle triangle, you will see that this square is greater than a square.
Let's see square to over here.
In the case of a right angle, Triangle B Square is equal to Equivalencies Square.
The case of an acute angle.
Triangle B Square is less than Esquibel Square, and in the case of an obtuse angle, triangle B square
is greater than is square.
Plus C Square is an interesting observation.
Let's take a triangle with sites for five and ten and say you want to find out whether this triangle
is a right angle triangle, an acute angle triangle or an obtuse angle triangle.
Let's take the biggest site, which is ten to ten square is gives you one hundred and four squared plus
five square.
That's sixteen plus twenty five.
Right.
How much is that.
That's forty one.
Right.
So you can see that under is greater than forty one.
Therefore it satisfies this criteria over here and hence we can conclude that a triangle with sides
or five and ten is an obtuse angled triangle.
