Pythagorean Theorem Day

By |2019-08-23T01:39:17+00:00August 15th, 2017|Categories: News|

No matter where in the world you are or how you write the date today (15/08 or 08/15), August 15 2017 is Pythagorean Theorem Day! 8² + 15² =17² OR  15² + 8² = 17² This doesn’t happen every year so it’s mathematically special!

Pythagorean Theorem Day or Pythagoras’ Theorem Day can be celebrated today, 08/15/2017 because the sum of the squares of the first two digits (8 & 15) equal the square of the last digit in the date (17).

The Mathletics Dictionary tell us that Pythagoras was a Greek philosopher and mathematician. He was born around 569 BC and died around 475 BC. He is most well-known for his theorem we celebrate today; c² = a² + b²
