They can also be called arms.
Yes. This angle has 2 rays connected by a point.
The second angle? angle B?
a vertex
Angle An angle is formed by 2 rays extending from the same endpoint.
The common endpoint of 2 rays that form an angle is the vertex.
Two rays that share a common endpoint are called an "angle." The common endpoint is known as the vertex, and the rays are referred to as the "sides" of the angle. Angles can be measured in degrees or radians, depending on the context.
2 rays
An angle is the union of two rays with a common endpoint.
The answer would be an angle.
no
NO
An angle separates a plane to 3 sets: 1) Points between the 2 rays 2) Points on one of the rays 3) Points outside of the 2 rays
