Pythagorean Theorem Day Celebration Ideas
It will be a few years before we get to celebrate the next Pythagorean Theorem Day in July of 2025. Here are some ideas for celebrating this fun mathematical holiday.
For many, the Pythagorean theorem (also known as Pythagoras’ theorem) is one of the most memorable formulas from high school math. Most adults would likely be able to rattle off a2 + b2 = c2 if prompted about the Pythagorean theorem even if they no longer know how to use the formula.
What is Pythagorean Theorem Day?
To qualify as a Pythagorean Theorem Day, the digits that make up the date must qualify as a pythagorean triple. The next pythagorean triple date will be on July 24, 2025 since 72 + 242 = 252.
Previously, Pythagorean Theorem Day was celebrated on August 15, 2017 since 82 + 152 = 172 and December 16, 2020 since 122 + 162 = 202.
Sometimes Pythagorean Theorem Day is known as Right Triangle Day.

Puzzle Solutions
Puzzle solutions are available on a password-protected solution page. I do not openly post the puzzle answer keys because one of my goals as a resource creator is to craft learning experiences for students that are non-google-able. I want teachers to be able to use these puzzles in their classrooms without the solutions being found easily on the Internet.
Please email me at sarah@mathequalslove.net for the password to the answer key database featuring all of my printable puzzles and math worksheets. I frequently have students emailing me for the answer key, so please specify in your email what school you teach at and what subjects you teach. If you do not provide these details, I will not be able to send you the password.
Not a teacher? Go ahead and send me an email as well. Just let me know what you are using the puzzles for. I am continually in awe of how many people are using these puzzles with scouting groups, with senior adults battling dementia, or as fun activities in their workplace. Just give me enough details so I know you are not a student looking for answers to the puzzle that was assigned as their homework!
