1. Map Scales and Angular Bearings

2. Types of Map Scales There are three main types of Map Scales:
Direct Statement: Written in words
Ex: 1 cm represents 1 km
Representative Fraction: Scale is written in numbers as a ratio.
Ex: 1:
Linear Scale: This scale is shown as a divided line.

3. Each of the map scale types are represented differently but have the same meaning.
Changing one scale to another is called scale conversion.
