The measure of an angle whose sides overlap is 0 degrees. It is than not an angle, but rather a line.
Inscribed angle
It is an inscribed angle.

It is an angle whose measure is 310/360 =31/36 of a full rotation.
The measure of an angle whose sides overlap is 0 degrees. It is than not an angle, but rather a line.
0 APEX!!
0 degrees
For the sides to overlap, the angle must be so wide as to double back over itself. Thus, it must be 360 degrees or greater.
-- an angle that measures 90 degrees -- an angle whose sides are mutually perpendicular
If it's a regular polygon and each exterior angle measures 72 degrees then it is a pentagon which has 5 sides
An inscribed angle is an angle whose vertex is on the circle and whose sides are chords.
