Question

Consider $\overleftrightarrow{RS}$ and $\overleftrightarrow{RS}$.Which is a chord and which is a secant?

Short answer

Chord:$\overline{RS}$.

Secant: $\overleftrightarrow{RS}$.

Step-by-step solution

Step 1. Given information. 

Figure is given.

Step 2. Concept used.

Chord: Any segment whose end lie on the circle is called chord of the circle.

Segment: It is a line which contains the chord.

Step 3. Now find .

Now it can be observed that $\overline{RS}$is a segment whose end $R$and$S$lie on the circle. So by above definition, it is a chord.

Also,$\overleftrightarrow{RS}$ is a line which contains the chord $\overline{RS}$, so by definition it is a secant.

Therefore, Chord is $\overline{RS}$and Secant is $\overleftrightarrow{RS}$.
