Question

the circle below has center o and diameter vu. ps intersects the circle at u, and rw intersects the circle at t and v. use this information to fill in the blanks. (a) give a chord. (b) give a secant line. (c) give a tangent line.

Explanation:

A chord is a line - segment that joins two points on the circumference of a circle. A secant is a line that intersects a circle at two points. A tangent is a line that touches a circle at exactly one point. By observing the given circle, we can identify the required lines.

Answer:

(a) A chord could be $\overline{TV}$ (joins two points on the circle).
(b) A secant line could be $\overleftrightarrow{RW}$ (intersects the circle at two points $T$ and $V$).
(c) A tangent line could be $\overleftrightarrow{MQ}$ (touches the circle at one point $Q$).
