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:
