How do we find the shortest distance from a given point on a line to another line? The shortest distance from any point on a line to another line will be the perpendicular distance from the point to the line; If the angle between the two lines is known or can be found then right-angled trigonometry can be used to find the perpendicular distance
So we have: d=\frac { \left| -6 \right| } { \sqrt { 3^ { 2 } { +4 }^ { 2 } } } =\frac { 6 } { 5 } . d = 32+42∣−6∣ = 56. The distance between a point and a line, is defined as the shortest distance between a fixed point and any point on the line.
The distance (or perpendicular distance) from a point to a line is the shortest distance from a fixed point to any point on a fixed infinite line in Euclidean geometry. It is the length of the line segment which joins the point to the line and is perpendicular to the line.
You can use haggis.math.segment_distance to compute the distance to the entire line (not just the bounded line segment) like this: d = haggis.math.segment_distance(P3, P1, P2, segment=False) Share
28 sie 2016 · Playing with the solutions, I built this simulation one of them: Using a vector equation of the line through $BC$. And Pythagoras's theorem to get the distance from $A$ to a point in the line. Minimised by using the point where the derivative equals 0.
