2. It is observed at A that point B is located at 60 degrees east of north and the distance is 500 meters. Then when observing point A from point B, point A is _______ of point B.
Review old knowledge
1. Method of determining position in plane:
(1) Use a pair of ordered numbers to determine the position;
(2) Determine position using distance and azimuth;
(3) Determine location using longitude and latitude;
2. Data that determines the position in the plane:
Determining the position of an object in a plane requires two pieces of data.
Method of determining position using "ordered number pairs":
(1) Determine the serial numbers of each horizontal row and the serial number of each column according to the conditions;
(2) Determine the position of the object by using the uniqueness of the intersection of the horizontal and vertical lines.
"Distance and azimuth" method to determine location:
(1) Determine the center position;
(2) Determine the azimuth angle and distance to the center of the object.
