step 1. draw a circle A step 2. draw a circle B with the same radius and with the origin on the circle A. step 3. connect the three points (origins of two circles) and any intersection of the circles with each other, and you get an equilateral triangle.

Oh those donuts meant center of the circle, that makes sense (thankies btw)

I woke up with this on my back, what does that mean?

okaaay... So:

Euclid (guy from ~2500 years ago) wrote a book called "Elements" where he described how various geometrical figures could be constructed with using only circles and straightlines (and their intersections).

This is one example from that book: How to construct the equilateral triangle.
