Pythagorean Theorem Day!

Dec 17, 2020 | Hamilton Mountain

As proof that the squares don’t have a monopoly on the math holidays, Pythagorean Theorem Day comes around periodically. Also known as Right Triangle Day, recognize Pythagorean Theorem Day whenever the sums of the squares of the month and day equals the square of the last two digits of the year. August 15, 2017 (8/15/17) and December 16, 2020 (12/16/20) are both Pythagorean Theorem Days.
