Square sets


As far as I could know both of these two drawing instruments you can see in the left are referred in English as "square sets".

To distinguish one from the other you have to point to properties they have as geometric figures, and that leads us to the questions I wanted you to answer.

• Why are these instruments like this, and no other way?
What does each one have in special, apart from a right angle?

• Have they to do with some regular poligons in some way? Which ones?
