Answer:

a.A line can be named either using two points on the line (for example, ↔AB ) or simply by a letter, usually lowercase (for example, line m ).

A ray is named using its endpoint first, and then any other point on the ray (for example, →BA ).

b.In naming a ray, we always begin with the letter of the endpoint (where the ray starts) followed by another point on the ray in the direction it travels. Since the vertex of the angle is the endpoint of each ray and our vertex is, each of our rays must begin with. Only fails to do so.

c.Two line segments are congruent if they have the same length. They do not need to have the same position or orientation.
