Scale Drawings

What is Scale Drawings?

A scale drawing represents a real object or route at a fixed ratio, so that every drawn length is the corresponding real length divided by the scale factor. The scale is written as a ratio such as 1 to 50 000, in which both sides are in the same unit. Directions on such a drawing are given as three-figure bearings, measured clockwise from a north line drawn at the point the bearing is measured from.

This definition is part of the Geometry chapter in Cambridge O Level Mathematics (Syllabus D).
