  2. Scale Drawings & Bearings Learning Intention Success Criteria • To be able to understand the term scale drawings. • 1. To understand the term scale drawing and how they are used in real life. 2. Interpret scale drawing into real-life measurements.

  3. Scales Definition A scale of 1 cm = 2m This simply means for every 1cm measured on a drawing this represents 2m in real-life.

  4. Scales In order to make sense of a map or scale diagram the scale must be known. For this scale model 1 cm represents 1m 4 cm This means for every 1 metre of the actual car, 1cm is drawn on the map.

  5. Scales The scale of this drawing is 1cm = 5m 6cm What is the actual length of the tree ? 30m 6 x 5 =

  6. Scales The scale of this drawing is 1cm = 90cm What is the actual length of the bus in metres ? 5cm 450cm 5 x 90 = 4.5m
