It may be nine days until Christmas, but today is the day to celebrate this December.
It’s Pythagoras Day: 16/12/20
Why?
Well 162 + 122 = 202
and
A Pythagorean triple is a set of 3 integers (whole numbers) a, b & c such that:
a2 + b2 = c2
And its nearly five years until the next Pythagoras Day: 24th July 2025, or 24 7 25
Happy Pythagoras Day!
