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.
I think I have the rulers you mentioned, and it is good to know that the Spike and Peaky blocks have nothing to do with my regular ruler.
But ... but .... but :!:
What am I supposed to do with that thirty degree angle? Why do they put things on the ruler that doesn't accomplish anything?
Oh ... let's see ... if I figure the 360 degree fact, divided by 30 = 12 ... hmm ... I can't remember which block that has been used with - - perhaps Mariner's star .... I LOVE numbers!
