Scale Drawings of Bearings

2. Accurate Scale Drawings
Make a sketch – (often given)
Use the scale to find the length of each line
Use a protractor to draw the angles accurately: Put protractor on NORTH LINE, cross on POINT.
Use a ruler & compass to draw the lengths accurately

3. A ship leaves the harbour and sails 30 km on a bearing of 040° and then sails 50 km on a bearing of 100.
Using a scale of 1 cm : 5 km, make a scale drawing of the ship’s course.
(b) Use your drawing to find the actual distance of the ship from the harbour.

4. 1. Sketch
