Drawing Bearings Using a Protractor | This video demonstrates how to draw bearings using a protractor, including cases where you are asked to draw a bearing of more than 180°. | Primary to Nat 4 | https://youtu.be/vdSZtVj1KvQ |
Scale Drawings Using Bearings | This video demonstrates how to make scale drawings involving bearings. It will help you to answer questions such as:
Ship A travels on a bearing of 050° from port for 6km, and Ship B travels from port on a bearing of 310° for 7.5km. How far apart are the two ships? | Primary to Nat 4 | https://youtu.be/VArC72z0gUc |
