The day of the Pythagorean theorem is celebrated on the day when the sum of the squares of the date and month is equal to the square of the year. The last time it was celebrated was on August 15, 2017 (15.08.17)
15 * 15 + 8 * 8 = 17 * 17.
The next holiday will be celebrated on December 16, 2020
(16.12.20)
16 * 16 + 12 * 12 = 20 * 20
Colleagues-mathematicians! Let's celebrate it with tasks, proofs, interesting facts. Lay out the materials on the board.
