The starting point for the measurement of horizontal lines typically refers to a reference line or baseline from which measurements are taken. This baseline is often established at a specific elevation, such as the ground level or a designated datum point, ensuring consistency in measurements. In architectural or engineering contexts, this could also involve using a level tool to ensure accuracy in alignment.
In linear perspective there is a horizon line and a vanishing point to which all non horizontal lines lead to. There are also vertical lines. Proportion lines are simply a starting point for an artist to determine the correct proportions of the portrait or picture.
The origin
It is called the origin, or the point (0, 0).
No. You have four corners, each with an odd number of lines going out. Each of these must either bee the starting point or the ending point, but you can only have one starting point and one ending point.
In mathematics, a baseline refers to a starting point or reference line used for comparison in various contexts. For example, in statistics, a baseline might represent a control group or initial measurement against which changes or effects can be evaluated. In graphical representations, it can denote the horizontal line that serves as a zero point for plotting data. Overall, a baseline provides a standard for measurement or analysis.

A horizontal ray in math is a line that runs horizontally that has one starting point and goes on forever in the opposite direction.
The starting point for elevation is typically referred to as the base or ground level. This is the point from which the measurement of elevation or height above sea level begins.
It is called the origin, or the point (0, 0).
The base of a wave is the lowest point of the wave where it meets the horizontal axis. It represents the starting point of the wave's oscillation.

The North and South Poles.
The origin of latitude measurement is the equator.
Very simply (and unimaginatively), the horizontal axis or x axis and the vertical or y axis.
