Exactly in the same way as using the formula for any straight line between two points which is:-
Square root of [(x1-x2)squared+(y1-y2)squared]
Subtract the y-coordinates of the points and take the absolute value
a chord
line segment
A chord is a line which connects two points which lie on a circle.

A vertical line goes straight up an down, so a vertical line segment is a line segment that goes straight up and down. Simple.

To find the perpendicular distance between two points, you can use the distance formula and the concept of perpendicular lines. First, calculate the distance between the two points using the distance formula. Then, find the slope of the line passing through the two points. The perpendicular distance is the length of the line segment that connects the two points and forms a right angle with the line passing through them.
A chord. If it's not a segment, it's a secant line.
