Triangles and rows

I had a Shakespeare professor who said "Three trees make a row," to confirm a pattern when a student noticed that something had appeared three times. I remember thinking, but not saying, "Not if they're making a triangle." But it wasn't a math class, and I understood his point.

There's something strong and fun about three. Two parents and a baby. A tripod for a camera or a telescope. A three-legged stool (a tripod to sit on). Three versions of a song. A book or movie trilogy. Counting by threes with its elegant stops at 33, 66, and 99.

European folklore has many sets of three, in bears, goats, wishes...

Here are other posts with photos of three things. It's a fun collection. Three (image label)
