Question

identify a term to describe each part of the circle. explain your answer.

1. $overline{oa}$
2. $overline{ge}$
3. $o$
4. $overline{np}$
5. line $overleftrightarrow{ab}$
6. $d$
7. $overline{jh}$
8. line $mn$

classify each arc as a major arc, a minor arc, or a semicircle.

1. $overarc{ac}$
2. $overarc{de}$
3. $overarc{fhi}$
4. $overarc{jml}$
5. $overarc{npq}$
6. $overarc{trs}$

Explanation:

1. $\overline{OA}$: Connects center $O$ to circle edge $A$.
2. $\overline{GE}$: Passes through center $O$, endpoints on circle.
3. $O$: Fixed point equidistant from all circle points.
4. $\overline{NP}$: Both endpoints lie on the circle, no center pass-through.
5. line $\overleftrightarrow{AB}$: Touches circle at exactly one point $A$.
6. $D$: Point where tangent line meets the circle.
7. $\overline{JH}$: Endpoints on circle, lies entirely inside the circle.
8. line $MN$: Crosses the circle at two distinct points.
9. $\widehat{AC}$: Arc smaller than a semicircle.
10. $\widehat{DE}$: Arc smaller than a semicircle.
11. $\widehat{FHI}$: Arc equal to half the circle.
12. $\widehat{JML}$: Arc larger than a semicircle.
13. $\widehat{NPQ}$: Arc equal to half the circle.
14. $\widehat{TRS}$: Arc smaller than a semicircle.
