true
½ the sum of the intercepted arcs.

true
½ the sum of the intercepted arcs.
It is the measure of half the intercepted arc.
15pi. after you add.
This is an uncommon term. I believe it means a circle which intersects a given circle orthogonally, i.e., with their arcs intersecting at 90 degrees.
Intersecting Lines
Adjacent Arcs
Either intersecting lines or perpendicular lines
Two or more lines that meet at a point are called intersecting lines.
coordinates
Either perpendicular lines if the lines create 90o angles or intersecting lines.
If they didn't intersect, then they couldn't be called intersecting lines.
