My fellow math enthusiasts and mathematicians let’s celebrate some triangles on this irregularly occurring holiday. This day doesn’t appear every year so it’s mathematically special!

Today I’m going to tell you about Pythagorean Theorem Day, how it is observed and how it’s celebrated. So keep on reading.

**What is Pythagorean Theorem?**

Pythagorean Theorem was discovered by a Greek mathematician and philosopher, Pythagoras who was known for this theorem. The theorem states the square of the hypotenuse of a right triangle when it is equal to the total sum of two adjacent sides which is a2 + b2 = c2.

**What is Pythagorean Theorem Day?**

This day doesn’t have a date in particular because it doesn’t come every year. It is celebrated when the total sum of the square of the month and days are equal to the square of the whole year. Thus, this holiday is celebrated on dates that meet these criteria.

**When is Pythagorean Theorem Day?**

The last time we celebrated this day was on December 16th, 2020. I’ll show you how you can find out:

**12*12 + 16*16 = 20*20 **

**44 + 256 = 400 **

**400 = 400**

Before this this day appeared on was on August 16, 2017

** 8*8 + 15*15 = 17***

**64 + 225 = 289**

** 289 = 289 **

So, this was cool, right? You can also find out when we will celebrate the Pythagorean Theorem Day and let us know in the comment section.

Also, I’ll give you a small hint that in this decade it will appear two times and after that, if the world allows us to live that long then it will appear in the year 2105! Crazy right, so let’s start celebrating this day and enjoy it to the fullest.

**How can you celebrate Pythagorean Theorem Day?**

By making the most of this uncommon holiday you can learn and understand more about Pythagorean Theorem and its applications, by eating foods that are cut in the shape of a right triangle (90 degrees) by baking cakes and cookies in a triangular shape and also try finding out when is the next Pythagorean Theorem Day appearing.

*Theorem*

His/her sense of humor was changed permanently by the Pythagorean Theorem.

Dima Zales

A lot of people think that Pythagoras proved the Pythagorean Theorem, but in fact, it remained unproven until Euclid’s time, centuries later.
