Today is one of the rare Pythagorean Theorem Days: it’s December 16, 2020, and 12² + 16² = 20² 📐
The next ones will be on July 24, 2025 and October 24, 2026.
@miramarco Made me curious about the angles of other days when the answer to arccos [(a² + c² - b²)/(2ac)] isn’t 1/4 turn.
@miramarco Because after 2026 there are no more integer pythagorean triples with a < 32, b < 13, c < 100. Math will be forever changed
