Parts of an Angle
An angle consists of the following parts :
- Arms of the Angle
- Vertex of the angle
- Initial Side
- Terminal Side
The image shown below shows the parts of an angle.
Arms of an Angle
The two rays that joint together to form the angles are called the arms of the angle. In the image added below, OP and OQ are the arms of the angle. The space between these two arms is the measure of the angle.
Vertex of an angle
The endpoint of the two arms of the angles is called the vertex of the angle. It is the point where the arms of the angle meet. In the above image added O is the vertex of the angle.
Angles Definition, Types and Examples
An angle is a figure which is formed by two rays or lines that share a common endpoint is called an angle. The word “angle” is derived from the Latin word “angulus”, which means “corner”. The two lines joined together are called the arms of the angle and the measure of the opening between them is the value of the angle between these two lines.
