No CommentsHow to Identify the Initial Side
Description
A detailed tutorial on the intial side of an angle. Step by step tutorial including several examples of the initial side of an angle for reference.
Overview
The initial side of an angle is the side of an angle where the measurement begins. An angle is always measured from the degree of zero to the degree of the angle, regardless of if the angle is positive or negative. The best display of an initial side would be when you draw angles with a protractor – the line that you trace along the bottom of your protractor forms a ray which is known as the initial side.
