180 degrees longitude?
180 degree longitude or 0 degree longitude means the same thing. Now when someone crosses this line one has to make some changes in the time e.g when one crosses this line and moves towards east it will gain one day, if one crosses and moves towards the west then one losses one day
What longitude and latitude line is at 0 degrees?
its the equator
Name the two invisible lines that divide the earth into four hemispheres?
The eastern and western hemispheres are separated by a single continuous line which passes through the geographical north and south poles. On the one side of the earth, it is the 0, or Greenwich, Meridian and, on the other (Pacific) side, it is the 180 meridian (which should not be confused with the International Date Line - though this approximates to the 180 meridian, it zig-zags across it repeatedly, at the behest of political convenience).
Where is a map showing the continents in the northern southern eastern and western hemispheres?
Most world maps will show you this. The northern and southern hemispheres are divided by the Equator, which will be visible on most world maps. Eastern and Western Hemispheres are not as strictly defined, but a dividing line defined by 0° (Greenwich) and 180° is common, as is one using 20°W and 160°E, which leaves the Americas on one hemisphere, and Africa and Europe entirely on the other.
Where does east end and west begin?
East and West technically don't end or begin, but there are lines of latitude that show where the Eastern and Western lines of latitude begin and end. The Prime Meridian, (0 degrees) runs through Greenwich, London, England, and any line of latitude away from it is labeled with the corresponding direction from the Prime Meridian. East and West lines end at 180 degrees, directly opposite the Prime Meridian.
How do you draw angles greater than 180?
First, if the angle is 360° or more, find the remainder of the angle divided by 360 - this is as 360° represents a full turn. If you have a 360° protractor just measure off the angle. If you only have a 180° protractor, then there are two ways it can be done as the protractor is marked so that 0° - 180° can be measured from either end of the base line: Method 1: excess over 180° 1) Subtract 180° from the angle to get the excess over 180°. 2) Place the protractor on the line, centred on the vertex of the angle on the left of the line, with the top 0°/180° mark on the line. 3) Measure the excess over 180° calculated in step 1 from the bottom 0° mark of the protractor. 4) Draw in the second angle arm - the reflex angle (measured clockwise) is as required. Method 2: acute/obtuse angle of the reflex angle to complete a full turn 1) Subtract the angle from 360° to get the angle which completes the full turn 2)Place the protractor on the line, centred on the angle vertex on the left of the line, with the top 0°/180° mark on the line. 3) Measure the angle to complete the full turn calculated in step 1 from the top 0° mark of the protractor (on the line). 4) Draw in the second angle arm - the reflex angle (measured clockwise) is as required. The above assume a clockwise angle is being drawn from a vertical line with the angle vertex at the bottom. For anticlockwise angles, place the protractor on the right of the line. For a non-vertical line [mentally] rotate the paper so that the first arm of the angle is vertical with the angle vertex at the bottom.
What is the length of the median that extends from the origin to the midpoint of the line segment of 12 0 and 0 -5?
Midpoint of line segment: (6, -2.5) Median line points: (6, -2.5) and (0, 0) Length of median line: 6.5
What is the coordinate of the midpoint of the segment -4 and 7?
If you mean that the line segment endpoints are (-4, 0) and (7, 0) then the midpoint is (1.5, 0)
What is the midpoint of line segment A -3 3 and B 3 -1?
The midpoint is (0, 1)
How could you find the y-coordinate of the midpoint of a vertical line segment with endpoint at (00) and (015)?
If you mean endpoints of (0, 0) and (0, 15) then the midpoint is at (0, 7.5)
How do you use protractor to measure to measure angle?
you will go to north protractor it means 0 and count up to the line of the angle example:
What is the midpoint of the line segment with endpoints -11 0 and 9 -1?
Points: (-11, 0) and (9, -1) Midpoint: (-1, -1/2)
Which method could you use to calculate the y-cordinate of the midpoint of a vertical line segment with endpoint (00) and (0-12)?
If you mean endpoints of (0, 0) and (0, -12) then the midpoint is (0, -6)
What is the midpoint of the line segment with endpoints 2 4 and 2 -4?
Endpoints: (2, 4) and (2, -4) Midpoint: (2, 0)
What is the midpoint of a segment whose endpoints are 4 0 and 0 2?
Midpoint of line from (4, 0) to (0, 2) is: ((4 + 0)/2, (0 + 2)/2) = (4/2, 2/2) = (2, 1)
What is the length and midpoint of the line segment joining the points of -6 1 and 6 6?
Length = 13 units Midpoint = (0, 3.5)
What methods could you use to calculate the x coordinate of the midpoint of a horizontal segment with the endpoints of -6 0 and 6 0?
You could use algebra (see below for how to do that), or you could graph the line and measure it.Using algebraThe x-coordinate of the midpoint of a line segment is the average of the x-coordinates of the end-points. 1/2(-6 + 6) = 0The y-coordinate of the midpoint of a line segment is the average of the y-coordinates of the end-points.1/2(0 + 0) = 0The midpoint of the given horizontal segment is the origin, (0, 0) .
