2 points determine a line.
Any 3 points determine a plane.
Three points can determine a plane but not 3-d space.
2 points determine a straight line and are always, by definition, collinear.
Where are the points!
you subtract both elevation and then that would be the elevation...
To determine elevation on a topographic map, look for contour lines that connect points of equal elevation. The elevation can be found by reading the numbers on these lines. The closer the lines are together, the steeper the terrain.
To determine elevation using a topographic map, look for contour lines that connect points of equal elevation. Find the contour line closest to your location and determine the elevation value listed on that line. Elevation can be calculated by adding or subtracting the contour interval value from the listed elevation.
The distance between two points must be known to determine the average slope between the two points. You must also know the change in elevation.
Watersheds are important to wildlife because they ensure that there is adequate rainfall and ground water. They assist the process through which ground water can evaporate and end up as precipitation once again. Watersheds are also important habitat for fish and other animals that need drink water often.
The reading on a leveling rod held at a point of known elevation is called a backsight reading. This reading is used as a reference point to determine the elevation of other points during leveling surveys.
Contour lines connect points with the same elevation or value, showing the shape and elevation of the land on a map.
The best way to find out if 2 points have equal elevation is to measure them. You must measure each of these points.
The elevation of a point that falls between two contour lines can be approximately determined by averaging the elevation of those two points. Assuming the point is somewhat halfway between the lines, this can be done by adding the elevations and dividing by two.
No. Three points do. Two points determine a line.
Points that are located at the same elevation above sea level are said to be at the same altitude. points A, B, and C are at the same altitude.
