Pythagorean triplets explained with examples

Know and learn complete details about Pythagorean triplets. Problems based on Pythagoras theorem can be solved easily if you know Pythagorean triplets.

Pythagorean triplets

Every time instead of applying Pythagoras theorem for finding sides of right angled triangle you can make use of this triplets.

First, it is required to know what is Pythagoras theorem. After that, we will study its triplets. Pythagoras theorem definition is given as “For a given any right angled triangle, hypotenuse square will be always equal to the sum of squares of remaining two sides”.

Pythagorean triplets

Here, Hypotenuse = RQ and the remaining two sides are PQ and PR.

Therefore, according to Pythagoras theorem statement, we can write it as

(Hypotenuse)2 = (side)2 + (side)2

(RQ)2 = (PQ)2 + (PR)2

Now we will study about Pythagorean triplets:

The numbers which satisfies Pythagoras theorem are called Pythagorean triplets.

Example:

3, 4, and 5 is one of the important Pythagorean triplets because 52 = 32 + 42, here the greatest number will be always hypotenuse.

The Formula for finding Pythagorean triplets:

The general notation of Pythagorean triplets is P2 – 1, 2P, P2 + 1 where P is an integer. 2P represents the least length (side) and P2 + 1 represents hypotenuse P2 – 1 represents another side of right angled triangle.

Example 1:

If 2P = 8

P = 4

Then P2 + 1 = 42 + 1 = 17

P2 – 1 = 42-1 = 15

Therefore, the triplets are 15, 8, 17 because 172 = 82 + 152

Example 2:

If 2P = 14

P = 7

Then P2 + 1 = 72 + 1 = 50

P2 – 1 = 72-1 = 48

Therefore, the triplets are 48, 14, 50 because 502 = 482 + 142
