In the figure,seg RM and seg RN are tangent segments of a circle with centre O.Prove that seg OR divides `/_MRN` as well as `/_MON`.

In the figure RQ is a tangent to the circle with centre O. If SQ=6cm , QR=4cm , find OR.

In figure, PQ and PR are two tangents to a circle with centre O. IF angleQPR=46^@ , then angleQOR equals (a) 67^@

In the adjoining figure, O is the centre of the circle. Seg AB, seg AC are tangent segments. Radius of the circle is r and l(AB) = r. Prove that , square ABOC is a square.

In the given figure , if TP and TQ are the two tangents to a circle with centre O so that anglePOQ=110^@ , then anglePTQ is equal to

In the adjoining figure, O is the centre of the circle. From point R, seg RM and RN are tangent segments drawn which touch the circle at M, N. If OR=10 cm, radius of the circle=5 cm, then find m /_MRN

In the figure , O is the center of the circle. From point R, seg RM and seg RN are tangent segments touching the circle at M and N. If OR = 10cm and radius of the circle = 5 cm, then (i) What is the length of each tanget segment ? (iii) What is the measure of /_MRO ? (iii) Whatis the measure of /_ MRN ?
