Question

Which of the following is a secant?

Answer 1

SV is a secant.

Explanation:

Let's understand some definitions.

• A chord is a line that has 2 endpoints at the circumference of a circle. A secant line is when you "extend" the chord to "outside" the circle. Secant line usually has arrows at both ends indicating they go on.

Another perspective is that the "chord is the part of the secant line that is within the circle".

• A diameter is a chord that goes through the center of the circle.

1. Out of the options, RU is inside the circle and goes through the center, so it's a diameter.
2. SV is a secant line, it goes on in two directions outside the circle and having 2 points in the circumference of the circle.
3. WS falls inside the circle ang DOES NOT go through the center, so it is a chord.

So SV is the secant line.

Answer 2

SV will be your answer. WS is a chord and RU is the diameter. the secent line will always be a continuing line A.K.A have arrows at the end of them
