As a matter of fact, I have made one of those half-square triangle quilts, but without the picture, I couldn't figure it.
so, then the 60 degree angle will either make an equilateral triangle or the sixty degree diamond.
Now!
What do we use the 30 degree line on our rulers for? Is that the angle that will make a Spike and Peaky block?
:D See what happens when you know a lot of things??? :?
Who started all this?
I sure appreciate the knowledge shared on this thread and throughout the site.
The Spike and Peaky Blocks are NOT 30, 60, 90 degree triangles. The skinny pieces have angles of approximately 63.4, 26.6, and 90 degrees, and the center piece has approximate angles of 63.4, 63.4, and 53.2 degrees.
The easiest way to get the right shape is to draw the blocks and then make templates. Or use the special ruler.
If one makes an equilateral triangle with 2 as its base, its height would the square root of three, which is less than 2.
