an angle precisely defined as the common endpoint of two rays
An angle consists of two rays called sides with a common endpoint called the vertex.
When two rays meet at a common endpoint, an angle is formed.
An angle is a figure made up of two noncollinear rays with a common endpoint. The common endpoint is called the vertex, while the two noncollinear rays are called the sides of the angle.
