Question

The sum of number of tangents that can be drawn from a point on the circle and a point outside the circle is ____

• A. 1
• B. 2
• C. 3
• D. 4

Answer 1

The correct option is C 3

Tangnet is a line which touches the circle at only one point.
Only one tangent can be drawn from a point on the circumference of a circle and two tangents can be drawn from a point out the circle as shown in the figure below.



Therefore the sum of number of tangents that can be drawn from a point on the circle and a point outside the circle
= 1+2 = 3.
