an angle is made from 2 lines so a circle does not have angles
An angle is made of 2 lines but aside is made of 1 line
The angle made by the incident ray with the normal is called the angle of incidence.
An included angle is the angle made by two lines with a common vertex.
An angle is made up of two intersecting lines, including their point of intersection.
