An angle is formed when two rays or line segments meet at a common end point. You must be familiar with lines, rays, line segments, and planes before we learn to name angles.
In these printable naming angles worksheets, you will learn to name angles in four different ways. The rules to name angles are given in detail in the charts below. The common meeting point of the angle is called the vertex. The two line segments or the two rays are the arms of the angle. The figure given below shows an angle with vertex and arms marked.
The last set of worksheets given here deal with exterior and interior of the angle.
All the points marked within the space enclosed by the arms are in the interior of the angle and the points marked outside the arms are in the exterior.
