Question

The horizontal angle between the north and the line joining the position of the observer and the object in a clock is called a __________.
a)Cardinal points
b)Bearing
c)Representative fraction
d)None of the above

Answer 1

Hint: Cardinal points are the four points in each direction. Bearing is horizontal angles and is also used for directions. Representative fraction is in the form of ratio.

Complete Answer: The horizontal angle between the north and the line joining the position of the observer and the object in a clock is called a bearing. Directions are often indicated by a system of angular bearing. Bearing is that the horizontal angle between the north and the line joining the position- of the observer and the object during a clockwise direction.
In navigation bearing the horizontal angle between an object and another object, or between it which is true north. Bearings can be measured in degrees.

Looking at the options given:
Option a: Cardinal points are the four main points on the compass. These are north, east, south and west. It is an incorrect answer.
Option b: The horizontal angle between the north and the line joining the position of the observer and the object in a clock is called a bearing. It is the correct answer.
Option c: Representative fraction is the ratio of distance on the map to the distance on ground. It is an incorrect answer.
Option d: none of the above cannot be the answer as one of the options is the correct answer i.e, bearing. It is an incorrect answer.

Option ‘b’ is correct.

Note: The bearing from the observer to the object is called forward bearing (FB). The bearing from the thing to the observer is named as backward bearing (BB).
