TERMS RELATED TO CIRCLE

The circumference is a geometric figure that is defined as the set of points that are at a constant distance from a central point called the center. Next, I present the main parts and lines of the circumference:

Parts of the circumference

1. *Center *: It is the central point of the circumference, equidistant of all points of the circumference.
2. *Radio *: It is the distance between the center and any point of the circumference.
3. *Diameter *: It is the distance between two opposite points of the circumference, through the center.
4. *Circumference *: It is the total length of the curve that forms the circumference.

Main lines of the circumference

1. *Diameter *: It is the line that passes through the center and joins two opposite points of the circumference.
2. *Radio *: It is the line that joins the center with any point of the circumference.
3. *Rope *: It is the line that joins two points of the circumference.
4. *Tangent *: It is the line that touches the circumference at one point and is perpendicular to the radius at that point.
5. *Secante *: It is the line that cuts the circle into two points.

Circumference angles

1. *central angle *: It is the angle that is formed in the center of the circumference between two radios.
2. *Registered angle *: It is the angle that is formed in the circumference between two strings.
3. *Tangential angle *: It is the angle that forms between a tangent and a radius at the point of tangency.
