### 方位

 There are 8 bearings that are commonly used in everyday life: east (E), south-east (SE), south(S), south-west (SW), west (W), north-west (NW), north(N) and north-east (NE)

${N}$${N}{E}$${S}{E}$${E}$${S}$${W}$${S}{W}$${N}{W}$

We can use the following methods to indicate precise bearings:

 (i) Reduced bearing All measured directions are in the form of N${x}^{\circ}$ E, N${x}^{\circ}$W, S${x}^{\circ}$E or S${x}^{\circ}$W, where ${x}^{\circ}$ is measured from north or south and 0 < ${x}$ < 90. In the figure, the reduced bearing of ${B}$ from ${A}$ is ${N}{75}^{\circ}{E}$ .

${N}$${A}$${B}$${75}^{{\circ}}$

 (ii) Whole circle bearing All measured directions are in the form of ${y}^{\circ}$, where ${y}^{\circ}$ is the angle measured clockwise from the north and ${0}\le{y}\le{360}$ . The integral part of ${y}$ is written in three digits. In the figure. the whole circle bearing of ${B}$ from ${A}$ is ${075}^{\circ}$ .

${N}$${A}$${B}$${75}^{{\circ}}$
