Distance To A Point By Measuring Two Fixed Angles
The coordinates and distance to a point can be found by calculating the length of one side of a triangle, given measurements of angles and sides of the triangle formed by that point and two other known reference points.
The following formulas apply in flat or Euclidean geometry. They become inaccurate if distances become appreciable compared to the curvature of the Earth, but can be replaced with more complicated results derived using spherical trigonometry.

Famous quotes containing the words distance, point, measuring and/or fixed:
“For time is the longest distance between two places.”
—Tennessee Williams (1914–1983)
“I have not made a study of it, but believe that it is a minor point in the history of the war.”
—Jean-Marie Le Pen (b. 1928)
“Man always made, and still makes, grotesque blunders in selecting and measuring forces, taken at random from the heap, but he never made a mistake in the value he set on the whole, which he symbolized as unity and worshipped as God. To this day, his attitude towards it has never changed, though science can no longer give to force a name.”
—Henry Brooks Adams (1838–1918)
“Museums, museums, museums, object-lessons rigged out to illustrate the unsound theories of archaeologists, crazy attempts to co-ordinate and get into a fixed order that which has no fixed order and will not be co-ordinated! It is sickening! Why must all experience be systematized?... A museum is not a first-hand contact: it is an illustrated lecture. And what one wants is the actual vital touch.”
—D.H. (David Herbert)
