The two circles will intersect in two points. An equilateral triangle can be constructed by taking the two centers of the circles and either of the points of intersection. In both methods a by-product is the formation of vesica piscis. The proof that the resulting figure is an equilateral triangle is the first proposition in Book I of Euclid's "Elements".
