Bearings Scale Drawing and Directions RESEARCH Explain what

Bearings, Scale Drawing and Directions RESEARCH Explain what a bearing is and through an example describe why you cannot have a bearing over 360°. What do the numbers at the end of all runways at major airports represent and can the two numbers at either end of a runway ever be the same? SKILL MEMORY N When you measure a bearing the protractor should always have 0° lined up facing North, you then measure the angle of turn for the bearing in a clockwise direction and write your bearing to the nearest integer making sure to use an extra 0’s at the front so the bearing has 3 digits. Q 1. What bearings represent the following directions? a) South b) NE c) SSW d) West Q 2. What bearing is in the opposite direction to a bearing of 225° ? Q 3. a) Draw accurately the following journey of a plane using a scale of 1 cm to 50 km. The plane sets off from London on a bearing of 285° and passes over Liverpool some 290 km from London before turning on a bearing of 225° to fly to Dublin some 215 km away. b) Use your drawing from part a) to find the real distance in a straight line from Dublin to London. c) What is the bearing of London from Dublin according to your scale drawing. CHALLENGE Describe through an example how you could use the properties of angles associated with parallel lines to calculate the bearing of say A from B if you knew the N bearing of B from A N Hint start with this sketch d) Check your answers using a suitable search engine. What percentage error was there in each of your measurements in b) and c)? A B
