The top plot represents the changing angular distance between the observed pointing and the sun, which is opposite to the interior angle located at the zenith (or the scattering angle).
One interior angle in a regular icosagon is 162, meaning that one exterior angle would be 18.
One interior angle in a regular tetracontagon is 171, meaning that one exterior angle would be 9.
A concave polygon will always have an interior angle with a measure that is greater than 180 degrees.
The dihedral angle is the interior angle between any two face planes.
Equivalently, a convex quadrilateral is cyclic if and only if each exterior angle is equal to the opposite interior angle.
Electrodes were constructed from silicon wafers to have three different sharpnesses (interior angle of 5 for sharp, 90 for medium, 150 for blunt).
Then one of the alternate angles is an exterior angle equal to the other angle which is an opposite interior angle in the triangle.
