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
Solution : Clearly, the man initially faces in the direction west direction that is along OA as shown in the figure.
Hence the correct option is D.
Illustration : Deepa moved a distance of 75 meters towards the north. She then turned to the left and walking for about 25 meters, turned left again and walked 80 meters. Finally , she turned to the right at an angle of . In which directions was she moving finally?
A. North-east B. North-west C. South-east D. South-west
Answer : D
Solution : Let us draw a diagram depicting the movement of Deepa . Assume that Deepa started from A,
Hence, the Correct Option is D.
Goori and Maaya standing with each other , they started a walk but Goori moved in south direction, covers a distance of 12 km and turns 900 clockwise and covers a distance of 18 km and reach to a Point. Similarly, Maya moved in east direction and turns 900 clockwise and covers a distance of 12 km, and than turns right and covers a distance of 30 km. What is the total distance covered by Goori? | |||
