Question

Answer the following questions:

() How many tangents are seen at a point of the circle ?

(i) Define secant of the circle ?

(ii) Ifr, and r, are the radi of two concentric circles and (r, >r). If the chord

of the larger circle AB touches the inter circle. Find the value of AB​

Answer 1

Answer:

Ans()- one tangent

Ans (i) - 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.

Ans (ii) - The length of the chord of the larger circle. Solution: We have given the two concentric circles which means both the circles have the same centre. The chord of the larger circle toches the inner circle so the chord of the larger circle will be the tangent of the smaller circle.
