Explanation:

Question 5: What are the two ways to name a line?

A line can be named in two main ways. First, by using two points that lie on the line, denoted with a line symbol above them (e.g., $\overleftrightarrow{AB}$ where $A$ and $B$ are points on the line). Second, by using a single lowercase letter (e.g., line $l$). These are the standard geometric conventions for naming lines.

A plane can be named in two common ways. One way is by using three non - collinear points that lie on the plane, denoted with the word "plane" before the points (e.g., Plane $ABC$ where $A$, $B$, and $C$ are non - collinear points on the plane). The other way is by using a single uppercase letter (e.g., Plane $P$). These are the accepted methods in geometry for naming planes.

A segment (line segment) is named by using the two endpoints of the segment with a segment symbol above them. For example, if a segment has endpoints $A$ and $B$, it is named $\overline{AB}$. This symbol and the use of the two endpoints clearly identify the specific segment.

Answer:

1. Using two points on the line with a line symbol above them (e.g., $\overleftrightarrow{AB}$).
2. Using a single lowercase letter (e.g., line $l$).
