Adjacent Arcs
From Latin: adjacere - "lie near"
Definition: Non-overlapping arcs with the same radius and center, sharing a common endpoint
Try this Drag one of the orange dots that define the endpoints of the two adjacent arcs. The red and blue arcs will adjust themselves to remain adjacent.
(If there is no image below, see support page.)
Adjacent arcs are two arcs on the same circle which
  1. Do not overlap, and
  2. Share a common end point.
This means they are, in effect, joined end to end to create a larger arc. In the figure above, drag any orange dot. The red and blue arcs will adjust to remain adjacent, forming a larger arc whose arc length is the sum of them.
The length of each arc can be added together to get the arc length of the larger arc.
