Tell us wether the line or segment is best described as a radius, chord, diameter, secant, or a tangent of 0O.

AB - secant

DB - diameter

AB - chord

OB - radius

BC - tangent

(In the order they are in the picture)

Step-by-step explanation:

AB - The line goes through the circle and does not go through the center. This fits  the definition of a secant, so line AB is a secant.

DB - Segment DB goes through the center and has endpoints on the circle. This fits the definition of a diameter, so DB is a diameter.

AB - Segment AB has endpoints on the circle and does not go through the center. This fits the definition of a chord, so segment AB is a chord.

OB - Segment OB is basically from the center to a point on the circle. This fits the definition of a radius, so segment OB is a radius.

BC - Line BC intersects the circle in only one point and does not go through it. This fits the definition of a tangent, so line BC is a tangent.
