Q-12
Answer the following questions :
(1) How many tangents are seen at a point of the circle ?
(ii) Define secant of the circle ?
(iii) If r1, and r2, are the radii of two concentric circles and (r1>r2) If the chord
of the larger circle AB touches the inter circle. Find the value of AB​

Answer 1

In geometry, a secant of a curve is a line that intersects the curve at a minimum of two distinct points. ... The word secant comes from the Latin word secare, meaning to cut. In the case of a circle, a secant will intersect the circle at exactly two points.

Answer 2

Step-by-step explanation:

1) only one seen tangent in circle at one point.

2) secant intersects the circle exactly at two points. It is drawn from outside the circle.
