Concept Used:
Theorem 8-2: The Square of the hypotenuse is equal to the sum of the squares of the base and perpendicular in a right triangle.
Theorem 8-5: If
Consider the given below:
Consider the right triangle
So, by theorem 8-2,
Taking square root both sides,
Now consider the right triangle
So, by theorem 8-2,
Taking square root both sides,
This implies that,
Now, consider the triangle
Let the longest side of the triangle
Now,
Now find sum of the squares of other two sides
It can be observed that,
That is,
So, by theorem 8-5,
