Squares and Square Roots Class - VIII Module 2/4 PYTHAGOREAN TRIPLETS The set of three numbers are called Pythagorean triplet if the sum of the squares of smaller numbers is equal to the square of largest number Prepared by Bashuki Nath, AECS, Anupuram
Squares and Square Roots Class - VIII Module 2/4 PYTHAGOREAN TRIPLETS General form for Pythagorean triplet is 2m, m2 1 and m2 + 1 Prepared by Bashuki Nath, AECS, Anupuram
Squares and Square Roots Class - VIII Module 2/4 PYTHAGOREAN TRIPLETS All Pythagorean triplets may not be obtained using general form. For example another triplet 5, 12, 13 also has 12 as a member. Prepared by Bashuki Nath, AECS, Anupuram
Squares and Square Roots Class - VIII Module 2/4 PYTHAGOREAN TRIPLETS Some Pythagorean triplets are 6, 8, 10 20, 21, 29 20, 99, 101 9, 40, 41 3, 4, 5 5, 12, 13 7, 24, 25 8, 15, 17 Prepared by Bashuki Nath, AECS, Anupuram
Squares and Square Roots Class - VIII Module 2/4 PYTHAGOREAN TRIPLETS If you multiply any Pythagorean triplet with any constant, the resulting set will again the Pythagorean triplet. (3, 4, 5) is a Pythagorean triplet (3, 4, 5) 2 = (6, 8, 10) is also a Pythagorean triplet (3, 4, 5) 3 = (9, 12, 15) is also a Pythagorean triplet (3, 4, 5) 7 = (21, 28, 35) is also a Pythagorean triplet Prepared by Bashuki Nath, AECS, Anupuram
