Take the coordinates of two points you want to find the distance between. Call one point Point 1 (x1,y1) and make the other Point 2 (x2,y2). It does not terribly matter which point is which, as long as you keep the labels (1 and 2) consistent throughout the problem.

The distance formula, d=√(x2−x1)2+(y2−y1)2 d = ( x 2 − x 1 ) 2 + ( y 2 − y 1 ) 2 , is derived from the Pythagorean theorem and gives us the distance between any two points, (x1,y1) ( x 1 , y 1 ) and (x2,y2) ( x 2 , y 2 ) , in a rectangular coordinate plane.

Distance formula d = |a1x1+b1y1+c1| / √a12+b12 , where d is the distance between two parallel lines. x1 and y1 are the two intersection points of the lines with the axis in a cartesian plane, while a1 and b1 are the coefficients of variable x and y of the line.

The distance formula states that the distance between two points in xyz-space is the square root of the sum of the squares of the differences between corresponding coordinates. That is, given P1 = (x1,y1,z1) and P2 = (x2,y2,z2), the distance between P1 and P2 is given by d(P1,P2) = (x2 x1)2 + (y2 y1)2 + (z2 z1)2.

Pick two points on the line and determine their coordinates. Determine the difference in y-coordinates of these two points (rise). Determine the difference in x-coordinates for these two points (run). Divide the difference in y-coordinates by the difference in x-coordinates (rise/run or slope).

For this divide the values of longitude and latitude of both the points by 180/pi. The value of pi is 22/7. The value of 180/pi is approximately 57.29577951. If we want to calculate the distance between two places in miles, use the value 3, 963, which is the radius of Earth.

You usually use DDE with polar tracking turned on to specify distances in particular directions. You can also combine DDE with Ortho mode to specify a distance in an orthogonal direction (0, 90, 180, or 270 degrees).

Where (x′,y′) are coordinates of the point. Since you want distance of line from origin, the coordinates become (0,0) and hence the perpendicular distance of a line from origin is |Ax′+By′+c√A2+B2|=|0+0+c√A2+B2|=|c√A2+B2|.

convert the known lat/lon coordinate to a cartesian coord (easting,northing). determine the x and y differences between (1) and the local coordinate of that point. apply this coord difference to to each of the 3 corners local coordinate. convert (3) back to geographical lat/lon.

A bearing is a direction. Bearings are measured clockwise from north, so north is zero degrees, east is 90 degrees, south is 180 degrees, and west is 270 degrees. In trigonometry, an angle is a measure of rotation from one ray to another ray with the same endpoint.
