How do you find the distance between 4 points?

To calculate the distance between a point and a straight line we could go step by step (calculate the segment perpendicular to the line from the line to the point and the compute its length) or we could simply use this ‘handy-dandy’ equation: d = |Ax1 + By1 + C | / √(A2 + B2) where the line is given by Ax+By+C = 0 and …
