DIRECTION & DISTANCE
Concept of Direction
In our day to day life, we make our concept of direction after
seeing the position of sun. In fact, this is a truth that sun rises in
the East and goes down in the west. Thus when we stand facing
sunrise, then our front is called East while our back is called
West. At this position our left hand is in the Northward and the
right hand is in the Southward. Let us see the following direction
map that will make your concept more clear:

Note:
On paper North is always on top be while South is always in
bottom.
Concept of Degree
Let us see the following picture:
Concept of Turn
Right turn = clockwise turn
Left turn = Anti-clockwise turn.
Let us understand it through pictorial representation
Important Point Regarding Direction
(1) If our face is towards North, than after left than our face will
be it towards West while after right turn it will be towards
East.
(2) If our face is towards South, then after left turn our face will
be towards East and after right turn it will be towards West.
(3) If our face is towards East, then after left turn our face will
be to North and after right turn it will be towards South.
(4) If our face is towards West, then after left turn our face will
be towards South and after right turn it will be towards
North.
(5) If our face is towards North-West, then after left turn our
face will be towards South-West and after right turn it will
be towards North-East.
(6) If our face is towards South-West, then after left turn our
face will be towards South-East and after right turn it will be
towards North-West.
(7) If our face is towards South-East, then after left turn our
face will be towards North-East and after right turn it will be
towards South-West.
(8) If our face is towards North-East, then after left turn our
face will be towards North-East and after right-turn it will be
towards South-East.
Concept of Minimum Distance
Minimum distance between initial and last point
h2 = b2 + p2, where
h = Hypotenuse
b = Base
P = Perpendicular
Remember this important rule is
known as ‘Pythogoras Theorem’
