Improvised Angle Measuring Methods

Other devices like protractors, theodolites, clinometers, etc will not be considered here because they are designed to measure angles and so do not represent an improvised technique. Some of the improvised angle measuring techniques we will discuss, however, are:

Measuring Angles with a Watch

Measuring Angles with Handspans

Measuring Angles with a Piece of String

Measuring Angles with Paces

Estimating Angles

The sun and moon each subtend an angle of about 0.5 degree from the earth. Angles of about this size can be estimated by comparing with the apparent size of the sun or moon.
