  4. How to measure and show direction? There are three ways to show direction • Compass point • Whole circle bearing • Reduced bearing

  5. 1.Compass point N NW NE W E SW SE S

  6. 2.Whole circle bearing • Show the direction in bearings by using a protractor. • It starts from north in a clockwise direction. • The direction of one place from another is described by the number of degrees measuring from north.
