Begin at the north-west and work your way counterclockwise for 90 degrees. Begin in the south-west and make three anticlockwise right angles. Begin at the north-east and work your way clockwise. This is called a 'full circle'.
There are 360 degrees in a full circle. Anticlockwise means opposite or reverse the clock's direction. So, going anticlockwise means turning 90 degrees more than going clockwise.
A degree is part of a larger unit called a 'grade'. There are 100 miles on a modern highway equaling about 1 degree. A quarter circle is 25 degrees. Three quarters of a circle is 9/10 of a degree. One eighth of a degree is 0.007854 degrees.
An anticlockwise quarter circle is 11/4 degrees. The answer can be found by multiplying 90*11/4=99 degrees.
It rotates 180 degrees clockwise, resulting in a South-East orientation. Spins 270 degrees anticlockwise, resulting in a South-West orientation.
You spin 45 degrees anticlockwise. You're looking southeast. You perform a 45-degree clockwise turn. You're looking north-west.
East and west are perpendicular to north and south. The east is rotated clockwise from north to south. The polar opposite of east is west. Directions on the globe can be described in terms of either compass points or with reference to the location of major cities.
For example, "the queen is in London" means that you should go to the west end of London and look for a large building that says "The Queen's London Palace." However, it is also possible to say "the queen is in London" if you are in Canada and mean that her office is in Toronto. In this case, you would go to the west end of downtown Toronto and look for a large white building with the words "The Queen's York Palace" on it.
Major cities are usually well-marked on most globes. If not, they can be found by looking at a map first. Once you have located a city on a globe or online, find the place where east and west intersect. This will be the center of the city.
For example, if you were to look at a map of London, you would see that the centre of town is somewhere near Hyde Park.
They are at a 90-degree angle to one another. (a) If we start facing South and turn clockwise to the West, we form one right angle. (b) If we start facing North and turn anticlockwise to the East, we produce two right angles.
Thus, a person who turns from east to north makes a 90-degree angle with the original direction they were heading in.
This is important because it tells us that if you are walking north on Main Street and then turn west, there is no point in which you could say you are back where you started from. The only way to return to your original position is if you keep walking west or turn around and walk east.
If you stop walking after turning west, you have gone too far and are now standing at a partial angle instead of a full one. If you continue walking after turning west, you will never reach your starting point again.
Similarly, if you walk south on Main Street and then turn east, there is no point at which you could say you are back where you started from. The only way to return to your original position is if you keep walking south or turn around and walk north.
If you stop walking after turning east, you have gone too far and are now standing at a partial angle instead of a full one.
You will be facing south if you turn 180 degrees clockwise or anticlockwise. Which way would you be facing if you were facing north and then rotated 180 degrees anticlockwise?
This question comes up very often in discussions about physics problems where someone needs to know which direction they should rotate an object to face another different direction. The answer is that it doesn't matter; you can rotate any object anywhere at all in space.
It's important to understand that rotating an object around a central point does not change its orientation. So if you're given the task of turning a book over so that its back is now faces down, there are two ways you could do this: You could simply lift the book up and then drop it, or you could first rotate it around its center of mass (which is usually near its base) by some small amount, and only then drop it. In either case, when it hits the ground it will still be on its back.
Orientation is a property of objects relative to each other, not relative to space itself. If I ask you "Which way is north?" and you say "North is up", I know that you are referring to vertical direction, but that doesn't depend on whether you're standing upright or lying down.
After 45 degrees clockwise, 180 degrees clockwise, and 270 degrees anticlockwise, the guy is facing south-west (90 deg clockwise). Unless you're in the South Pole, in which case you're still looking north.
