In what direction will your friend return home from school if he went to school azimuth 45 degrees; 90 degrees?

In order to answer this question, you must be able to use the azimuth and know its directions.

Azimuth can be compared to a mechanical watch, in which one hand is at the 12 o’clock position, while the other is spinning. The angle between these arrows will be the azimuth.

This is the angle between north and any other direction.

Main azimuths of directions:

North – 0о, 360о;

North-east – 45o;

East – 90o;

South-east – 135o;

South – 180o;

Southwest – 225о;

West – 270o;

Northwest – 315о.

Case 1.

If he walked along the 45 ° azimuth, this means that he was going north-east, which means that he will return in the opposite direction to the south-west. 225о in azimuth;

Case 2. Walked 90 ° in azimuth – to the east, returned 270 ° in azimuth – to the west.
