9/12/15 — Happy Right Triangle Day!

Published by MrHonner on

Happy Right Triangle Day!  Today, on 9/12/15, we celebrate a favorite triangle:  the 9-12-15 right triangle.

9-12-15 Triangle

We know this triangle is right because the side lengths satisfy the Pythagorean Theorem.

9^2 + 12^2 = 15^2

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.
