What is "in the diagram of circle p?

In a diagram of a circle p, several key elements and relationships can be identified. These include:

  • The Center: This is the central point p from which all points on the circle are equidistant. It is often labeled as the center of the circle.

  • The Radius: Any line segment that connects the center p to a point on the circle. All radii of a given circle are of equal length.

  • The Diameter: A line segment that passes through the center p and connects two points on the circle. The diameter is twice the length of the radius.

  • A Chord: A line segment that connects any two points on the circle. The diameter is the longest chord in a circle.

  • An Arc: A portion of the circumference of the circle.

  • A Tangent: A line that touches the circle at exactly one point. This point is called the point of tangency. The tangent line is perpendicular to the radius at the point of tangency.

  • A Secant: A line that intersects the circle at two points.

  • Central Angle: An angle whose vertex is at the center p of the circle.

  • Inscribed Angle: An angle whose vertex lies on the circle and whose sides are chords of the circle.
