,• Radius,: The distance from the centre of the circle to its outer rim.
• Chord,: A line segment whose endpoints are on a circle.
• Diameter,: A chord that passes through the centre of the circle. The length of a diameter is two times the length of a radius.
• Secant,: A line that intersects a circle in two points.
• Tangent,: A line that intersects a circle in exactly one point.
• Point of Tangency,: The point where a tangent line touches the circle.
