Question

Identify the right option for the image shown below.

• A. Lines RO and PO are the only radii of the given circle.
• B. Lines SO and TO are the only radii of the given circle.
• C. Lines PO, RO, TO and SO all are radii of the given circle.
• D. Lines PO, RO, TO, PQ and SO all are radii of the given circle.

Answer 1

The correct option is C Lines PO, RO, TO and SO all are radii of the given circle.

All the lines PO, RO, TO and, SO are the radii of the given circle because these lines join the centre and the boundary (circumference) of the circle.
The line PQ is the only line which is not the radius. The line PQ is known as chord.

So, option C is the right answer.
