What does "Recs" mean?
 

I bought a Craftsy class and the teacher is showing a "Recs" ruler? What does the term stand for?

I think this might explain it for you http://www.amazon.com/Wrights-1-Inch.../dp/B000AXVP4M

I thought it was short for rectangle because when you use a Tri-Rex ruler set for blocks you end up with a rectangle from 3 triangles.

I recently purchased Darlene Zimmerman & Joy Hoffman Tri-Recs for a particular quilt pattern I wanted to try. I know one can accomplish the same block without one, but I'm thinking it is much easier and more accurate, at least for me. When paired together the square is cut on grain. There are lots of fun projects to use the tool with. This is the pattern I am working on now laid out on my dinning room table.

I should have mentioned that when used with a different block, it can give the illusion of curves. Sorry repeat picture - don't know what happened?

So the Recs ruler lets you divide a rectangle into triangles? (And thanks for reminding me Amazon is there. I may do some ruler shopping before long. I don't know why I didn't think of it because I shop there all the time.)

Beautiful quilt top, Rainy. And I can see the faux curves. Lovely. It looks as though I will have to invest in a set of these... And what is the name of your quilt pattern?

Not exactly. The tri-recs ruler is actually a set of 2 rulers. They let you make a "squared triangle" or a "triangle in a square" unit, which is square. There's not a standard name for this unit. In the photo that RainyBC provided, it's the teal and white unit in the bottom row right under the purple square . The ruler is needed because the angles are hard to achieve (63.44, 63.44, and 53.13 degrees for main triangle) A rectangle is a 4 sided shape where all the angles are 90 degrees, so a square is actually a special kind of rectangle. End of geometry lesson for today. There will be a quiz tomorrow.

Please, no quizzes, LOL. My mind is blown anyway. I am not a math person and will have to re-watch these Craftsy lessons a second time for them to make sense, in a lot of cases.

To be sure I am getting the correct square from your description, as I look at the bottom row of blocks, if I count from the right over to the third block I see a largish purple square and below it is a square comprised of three triangles, one in turquoise/teal and the other two on top of the teal one in white. On either side of the block I am seeing are a pair of 4-patches. Is this the "squared triangle" you mention?
