Angles don't really have side lengths, and if they do, then those don't tell you anything
about the measure of the angle.
The sides of a 1-degree angle can be 1 millimeter long or they can be 1 light-year long.

No. Angles don't have anything called a side length. However, one can use trigonometry to compute the angles of a triangle based on the side lengths of the triangle (triangles do have side lengths).
If measured on the inside of the polygon, the it is an interior angle.
Angles are measured with a protractor in degrees, minutes and seconds.
Adjacent angles are simply two angles that are next to one another and share one side. There is nothing else unique about these angles, and they are measured as one would measure any other angles.
If one of the other angles is x (degrees or radians in any units), then the ratio is sin(x) : cos(x).
