Problems Involving Angles
Problems Involving Angles
Directional Questions : Direction is the information contained in the relative position of one point with respect to another point without the distance information. Directions may be either relative to some indicated reference or absolute according to some previously agreed upon frame of reference.
In these type of questions a statement is given describing the position and movement of an object or an individual. A successive follow-up of directions is formulated and the candidate is required to ascertain the final direction or the distance between two points. These questions are meant to judge the candidate,s ability to trace and follow correctly and sense the direction correctly.
The adjoining figure shows the four main directions (North N, South S, East E, West W) and four cardinal directions (North East NE, North West NW, South East SE, South West SW) to help the candidates know the directions.
Problems Involving Angles : In these type of question a person or an object starts moving at an angle or after moving in various directions turns at an angle.
When a person is facing towards north and he turns 3600 clockwise or anticlockwise he reaches to his starting direction always.
900 + 900 + 900 + 900 = 3600
900 + 900 + 900 + 450 = 3150
900 + 900 + 900 = 2700
900 + 900 + 450 = 2250
900 + 900 = 1800
900 + 450 = 1350
450 + 450 = 900
Illustration : A man is facing west. He turns in the direction and then another
in the same direction and then
in the anti-clockwise direction. Which direction is he facing now ?
A. South B. North-west C. West D. South-west
Answer: D
