Arm of An Angle Definition
The rays or lines used in forming an angle are known as an arm of an angle.
These rays have a common joining point that makes an angle that is also known as the vertex.
You can determine the measure of an angle by calculating the distance between two arms of an angle.
For a more precise understanding of a concept, let's have a look at the diagram listed below:
