My Darling B has been making a quilt with lots of little triangles on it and she wanted to know how long the sides of the triangles should be, which means she would have to a) draw the triangle on a piece of paper, then measure the sides of the triangle, or b) ask me for the equation she could use to calculate the length of each side of the triangle. She chose b).

I’m trying to think of a way to describe how outrageous it is that she would think I remember anything about geometry thirty-eight years after I last cracked open a geometry book. It would be sort of like asking an elderly aunt how to build a steam locomotive because you remember that she once read Thomas the Tank Engine to you when you were a child. That’s sort of close. I mean, I did actually study geometry, and I think I even got a passing grade at the end of the semester, but I’m pretty sure it was a C minus. The only thing I remember now about geometry is that A squared plus B squared equals C squared, but knowing that is of absolutely no use to me because my ruler doesn’t have squared numbers on it and I don’t remember how to unsquare numbers. I’m not sure I have ever known, now that I think of it.

So, much as I wanted to, I couldn’t help B solve the riddle of the triangles. “Ask the google,” was the only thing I could suggest. In the end, I think she just eyeballed it.
