Yes, the x-distance, y-distance, z-distance, or any combination of the three between any two points may be zero Not possible. If the distance between two points is zero then the points are the same.
yes, it is believed that the Romans used this method when extreme accuracy was necessary
A circleus.
They must be collinear.
If you mean: (-8, 4) and (5, 4) Then the distance between the points works out as 13
You must be talking about a compass, a directional tool.
i have no clue you try to figure it out
The curvature of the Earth affects the line of sight between two distant points by causing objects to appear lower than they actually are. This can result in obstacles blocking the direct line of sight between the two points, especially over long distances.
The Earth's curvature causes the line of sight between two distant points to be slightly curved, making them appear higher than they actually are. This can affect long-distance communication and navigation.
a calibrated instrument for measuring the potential difference between two points.
A flat map
The curvature of the Earth affects the line of sight between two distant points by causing objects beyond the horizon to be hidden from view. This means that the Earth's curvature limits how far we can see in a straight line without any obstacles in the way.
An instrument for measuring in volts the differences of potential between different points of an electrical circuit.

The base word of distance is "distance." It refers to the amount of space between two points, objects, or locations.
