Thanks for this, I have trouble with the 60, can you explain how the 30,60, and 90 works.. not sure I worded this right.

When in doubt about a block you see, check with a protractor. (Remember those half-circle pieces of plastic from geometry class?) You don't need to measure perfectly to know whether you have the correct tool.
