They are simply called intersecting arcs.
true
½ the sum of the intercepted arcs.
15pi. after you add.
Adjacent Arcs
Either intersecting lines or perpendicular lines
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.

The measure of an angle formed by two intersecting chords in a circle is equal to half the sum of the measures of the intercepted arcs. This means that if two arcs, ( A ) and ( B ), are intercepted by the angle, the angle's measure can be calculated using the formula: ( \text{Angle} = \frac{1}{2} (mA + mB) ), where ( mA ) and ( mB ) are the measures of the intercepted arcs. This relationship helps in solving various problems involving angles and arcs in circle geometry.
Either perpendicular lines if the lines create 90o angles or intersecting lines.
