But three is a cool number anyway. How about the three sides of a shape? That's what we'll deal with today. There's the triangle, which is the only (equilateral) real triangle. It's the only one I ever really remember because I finally made a neumonic for myself: equi means equal, and lateral means side. So equal sides is what makes a triangle. [Someone could have told me that 45 years ago!]
But there are also right triangles. And acute triangles. Obtuse triangles. Isosceles. Scalene. I imagine that there are triangles for any way you can think of drawing a triangle. So, as long as there are only three sides, you've got something in the way of a triangle.
Since we're into quilt-making, let's consider how to make a quilt with triangles. They don't have to be equilateral to work, but for this SQI, we're looking at real triangles. By the way, half-square triangles or HSTs, are right triangles, not equilateral triangles. Try not to get confused here.

2. Continue sewing pairs in this way until you have what may be enough for a row.

But you're working with triangles, so the sides will not be straight until you cut off the protruding triangles. I recommend that you sew one extra pair to every row. Now you'll sew 14 triangles to make your 36" row because you'll be straightening the sides out later.
