Vertical Angles
Technically, angles are made of rays that are 2-D, not 3-D. Only 3-D figures have sides. So, no.
Yes. An angle, by definition, is two rays with the same origin.
Perpendicular rays are two rays that intersect one another to form four right angles. Below is an image that shows two perpendicular rays.
An angle is formed by two rays with a common endpoint.
I don't think there are rays of naming. Angles are made up of 2 rays.
Angles are the degree measure between the two rays that make an angle. Vertices are the point in which the two rays meet to create that angle.
