Question : A line touches a circle of radius 6 cm. Another line is drawn which is tangent to the circle. If the two lines are parallel, then the distance between them is:
Option 1: 8 cm
Option 2: 12 cm
Option 3: 10 cm
Option 4: 6 cm
Correct Answer: 12 cm
Solution :
Let MN and PQ be two parallel tangents and AO = OB = 6 cm So, AB = AO + OB = 6 + 6 = 12 cm Hence, the correct answer is 12 cm.
