When a line segment connecting two points is horizontal the length of the segment can be found by finding the absolute value of the difference in x-coordinates of the two points.
I think that you draw a square from that line, and find the area of that square.
Subtract the y-coordinates of the points and take the absolute value
It is the circumcentre of the triangle formed by the three points. Draw the perpendicular bisectors of two of the lines joining the three points. They will meet at the point that is equidistant from the three points.
-- Find the distance between the endpoint and the midpoint.-- Double that distance to get the length of the complete segment.-- When you're finished, sit quietly for a moment and ponder the meaning of "midpoint".

Horizontal
x-coordinates :)

The distance formula providing you know the coordinates of its end points
Add the x-coordinates of the points and take the absolute value
Subtract the y-coordinates of the points and take the absolute value

On method would be to find the midpoint of the line segment and then to find the mid points of each of the halves.
Subtract the x-coordinates of the points and take the absolute value. Using the Pythagorean Theorem, the y-value would be zero, and the distance the square root of its own square.
