English: Geometrical construction diagram for Vesica Piscis figure, formed by the intersection of two circles of the same radius, where each circle's center is on the circumference of the other circle.

• Black: Vesica Piscis figure itself
• Light blue: Claimed "fishtail" extensions (when it is desired to approximate the Vesica Piscis to an Ichthys)
• Light red: Two equilateral triangles formed by drawing straight lines between the centers of the two circles, and between the circle centers and the points of intersection of the circles.
