Happy 5-13-12 Day!

In honor of today’s date, 5/13/12, I honor one of my favorite triangles:  the 5-12-13 triangle.

Of course, one reason this is a such a nice triangle is because it is a right.  We can easily see that the side lengths satisfy the Pythagorean Theorem

5^2 + 12^2 = 13 ^2

Another reason I like this triangle so much is because it plays a part in another of my favorite triangles:  the 13-14-15 triangle!
