## How do you find the shortest distance between two points on a sphere?

The shortest distance between any two points on the surface of a sphere is called **the Great Circle**, a part of which is shown in the diagram as a dashed line.

**great-circle distance, orthodromic distance**, or spherical distance is the shortest distance between two points on the surface of a sphere, measured along the surface of the sphere (as opposed to a straight line through the sphere's interior).

## Why is the shortest distance between two points?

No, a straight line isn't always the shortest distance between two points. The shortest distance between two points depends **on the geometry of the object/surface** in question. ... If we were living on a flat earth (which we don't) then yes, a straight line would be the shortest distance between points A and B.Nov 13, 2021

### Why great circles are the shortest distance?

(iii) Great Circles are the shortest routes between two places **as we can connect any two places on the earth's surface by the curvature line of the great circle**. And this curvature is the smallest possible route between those two places, because this curvature directly connects those places or points.

### How do you find the arc length between two points on a sphere?

If the sphere has radius R, so will all its great circles; so the length of an arc is **exactly R times the radian measure of the central angle it intersects** (or R times (π/180) times the measure of that angle in degrees).

### How do you find the shortest distance?

The shortest distance between the two points is the length of the straight line drawn from one point to the other. The formula for the shortest distance between two points or lines whose coordinate are (xA,yA), ( x A , y A ) , and (xB,yB) ( x B , y B ) is: **√(xB−xA)2+(yB−yA)2 ( x B − x A )** 2 + ( y B − y A ) 2 .

Distance between Two Parallel Lines

It is equal to the length of the perpendicular distance from any point to one of the lines. Let N be the point through which the perpendicular or normal is drawn to l_{1} from M (− c_{2}/m, 0). We know that the distance between two lines is: **d =|Ax _{1} + By_{1} + C| / (A^{2} + B^{2})^{½}**.
