A chord is a line segment with each endpoint on the circle A diameter is a chord that passes through the center of the circle. A secant of a circle is a line that intersects a circle at exactly two points 1. Draw a chord 2. Draw a diameter 3. Draw a secant

A tangent of a circle is a line that intersects a circle at exactly one point. The point of intersection is called the point of tangency. Draw a line tangent to circle O with a point of tangency at Wesley. A central angle is an angle whose vertex is the center of the circle. An inscribed angle is an angle whose vertex is on the circle.
