Answer:
In the adjoining figure , O is the centre 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=5cm, the
(1) What is the length of each tangent segment?
(2) What is the measure of ∠MRO ?
(3) What is the measure of ∠MRN ?
answer.∠OMR=∠ONR=90
