They are simply called intersecting arcs.
Circles have infinitely many arcs, not just 3.
Adjacent Arcs
They are arcs of congruent circles.

An oceanic-oceanic convergence occurs when two plates made of oceanic crust collide. This collision can lead to the formation of deep oceanic trenches, volcanic island arcs, and earthquakes. Over time, the denser plate may subduct beneath the other, leading to the recycling of oceanic crust back into the mantle.
Volcanic arcs form at plate subduction zones. Island arcs are volcanic islands that form over "hot spots" in the Earth's mantle. Because the islands are moving with the oceanic plate, they eventually are removed from the hot spot, forming a chain of islands in the direction of the plate movement.

Volcanic island arcs are likely to result from convergent boundaries where an oceanic plate subducts beneath another oceanic plate or a continental plate. The subducted plate can melt, causing magma to rise and form a series of volcanic islands above the subduction zone.
Volcanic arcs are usually island arcs off the coast of a continent, while volcanic mountain ranges are usually inland inside a continent. But the volcanoes of a volcanic island arc do form an undersea volcanic mountain range. So to some extent the difference is mostly a matter of terminology.
Mountains, volcanic islands, and island arcs.
Volcanic arcs form at plate subduction zones. Island arcs are volcanic islands that form over "hot spots" in the Earth's mantle. Because the islands are moving with the oceanic plate, they eventually are removed from the hot spot, forming a chain of islands in the direction of the plate movement.
