# An Angle Results From The Intersection Of Two Rays At The Vertex

## Below Are The Details Of An Angle In Geometry

The following are the unique characteristics of

**Angle In Geometery**.

- A
**Angle**is created when two**Rays**intersect called the vertex. See diagram below; intersection of rays (Line) AB and AC for vertex A. - The intersection of the two rays is called the
**Vertex**. - There is a standard method of labeling angles. First label
the vertex; we choose to label it
**A**. The two rays are labeled Points**B**and**C**. - The Degree of the angle between two Rays
is determined by the space between the rays. See diagram below.
One ray is horizontal thus giving us a reference point. The distance of separation
between Rays
**B and C**determines the angle's value. - Is there a standard way of writing an angle as a mathematical
expression? The answer is yes. Here are the details: (1) All angles must start with
the
**∠**character. (2) The vertex must be the center label when writing an angle. (3) Valid angle statements in this example are**∠BAC**and**∠CAB**.

There are many

**types of angles**:
