Name the following part from the figure where $O$ is the centre of the circle: $\bar{A O}$ , $\bar{A B}$ , $\bar{B C}$ , $\bar{A C}$ , $\overset{⏜}{D C B}$ , $\overset{⏜}{A C B}$ , $\bar{A D}$ and shaded region.

Accepted Answer

Radius is a line segment that joins centre and a point on the circumference of a circle.

In the figure, $O$ is the centre and $A$ is a point on the circumference.

So, $\bar{A O}$ presents the radius of the circle.

$\bar{A B}$ : It is the diameter of the circle. From the image, it is clear that it is the largest chord passing through the centre.

$\bar{B C}$ : It is a chord that joints two points $B$ and $C$ on the circumference as chord is a line segment that joints two points on the circumference.

$\bar{A C}$ : It is also a chord of the circle whose endpoints are $A, C$ , two points on the circumference.

$\overset{⏜}{D C B}$ : It is the major segment of the circle as it is bounded by major arc and chord $D B$ . It is larger than a semicircle.

$\overset{⏜}{A C B}$ : It is a semicircular region as the semicircular arc is intercepted by diameter $A B$ .

$\bar{A D}$ : This is a chord of the circle.

Shaded region: It is the minor segment $(\overset{⏜}{D X B})$ of the circle. The piece of circle is intercepted by a chord $D B$ and it is smaller than a semicircle.
