9/12/15 — Happy Right Triangle Day!
Happy Right Triangle Day! Today, on 9/12/15, we celebrate a favorite triangle: the 9-12-15 right triangle.
We know this triangle is right because the side lengths satisfy the Pythagorean Theorem.
It’s actually been less than a month since we last celebrated a Right Triangle Day, but they are rare, so enjoy being right today!

Every day is a right triangle day, if we aren’t necessarily in Euclidean geometry.

For the record, mathematician/artist Henry Segerman notes that you still need a triple to satisfy some form of the triangle inequality.
