If the square of the greater number is equal to the sum of the squares of the remaining numbers then the numbers form a Pythagorean triplet or the numbers form a right angle triangle.

The only thing we require while solving these examples are we should know the squares of the numbers mentioned in the example and then we can solve these examples easily.

The questions answered in this section are given below :

1. Find the Pythagorean triplets from among the following sets of numbers.
   (i) 3, 4, 5 (iii) 4, 5, 6 (v) 9, 40, 41 (ii) 2, 4, 5
   (iv) 2, 6, 7
   (vi) 4, 7, 8

2. The sides of some triangles are given below. Find out which ones are right-angled
   triangles?
   (i) 8, 15, 17 (v) 40, 20, 30

In this way the problems based on Pythagoras theorem are solved and whether the given numbers form a Pythagorean triplet or not is determined.
